Don’t Rawdog Your Life: Why Discomfort Is Not Automatically Growth

Friction-Maxxing, Why Harder Is Not Always Better

[This DrP article was first published on NextEvolutionPerformance]

The same generation dusting off vinyl records, film cameras, handwritten letters and phones that do little more than make calls is also deliberately putting inconvenience back into life.

People are deleting delivery apps so food requires more thought. They are walking rather than ordering a car, listening to an album from beginning to end and choosing hobbies that cannot be completed by swiping impatiently. The label is friction-maxxing: intentionally reintroducing effort, delay or inconvenience into a culture that has become almost aggressively seamless.

There is an intelligent idea inside this. Then the internet does what the internet does. It removes the discernment, adds an endurance leaderboard and converts a sensible principle into another performance fetish.

Hence people “rawdogging” long-haul flights— staring at the flight map without books, music or films. The more theatrical versions reportedly involve refusing food, water, sleep or movement, as though dehydration were evidence of exceptional character.

So, let’s get our geek on.

What are hormesis and entropy?

Hormesis is an adaptive response to an appropriately dosed challenge. Entropy describes the dispersal of energy and the tendency of unattended systems to drift.

In physics, entropy is not merely a grand word for mess. It relates to how energy is dispersed and, in statistical mechanics, the number of microscopic arrangements compatible with a system’s visible state. In an isolated system, total entropy tends to increase.

As a metaphor for life, this is useful. The inbox grows. The cupboard fills. The body deconditions. The temporary workaround becomes company policy. The small pain you keep ignoring changes how you sit, walk and sleep. The relationship full of unspoken resentment becomes more difficult to repair.

Useful order requires intelligent energy.

Hormesis, by contrast, describes adaptive responses to moderate challenges that can improve function or tolerance. But the effect is dose-, timing- and context-dependent. A manageable exposure may stimulate adaptation; a larger, sustained or badly timed exposure can cause harm.

Why does this matter? Because not everyone needs to rawdog their way through a fourteen-hour flight— remaining immobile and refusing water— to prove absolutely nothing. Sitting without entertainment may be a useful experiment in boredom. Prolonged immobility during long-distance travel is a recognised risk factor for venous blood clots, particularly for people with additional risks. Maintaining hydration is reasonable, although hydration itself has not been proved to prevent travel-associated clots.

Do not confuse surviving a stupid decision with becoming stronger.

Not all hard things are good. Not all easy things are bad.

Discomfort is not proof that growth is occurring.

Friction is not the goal. Compounding is.

First, we decided that everything should be frictionless.

Now, apparently, everything must become intentionally difficult. Convenience is laziness. Pleasure is weakness. Regulation is avoidance. Rest is fragility. Pain is progress.

But high performance is not the ability to endure the maximum available discomfort. It is the ability to discern:–

  • what should become easier because its benefits compound;
  • what should become harder because it repeatedly harms you;
  • which resistance builds a capacity you genuinely need;
  • and which strain is merely consuming the body and brain expected to carry your future.

Some friction develops capability. Some friction is simply badly designed life. A needlessly complicated system does not build character. It consumes Mental Capital that could have been invested somewhere important.

What friction-maxxing gets right

Modern ease can weaken selected capacities. I have watched intelligent clients become so accustomed to AI that they hesitate to write a basic email without consulting it. Some no longer know how to answer an ordinary chat message until a machine has made it warmer, clearer, more diplomatic and apparently incapable of offending any living organism.

AI is not the enemy. But what you repeatedly outsource, you may stop rehearsing.

The same applies to boredom. Every unfilled moment now seems to require a snack. Sometimes potato chips. Sometimes reels. Both are immediate, intensely consumable and conveniently packaged so that you never need to experience the awkward few minutes before your own thoughts arrive.

A 2026 meta-analysis found a moderate association between boredom proneness and problematic use of digital technologies. This does not prove that boredom directly causes compulsive technology use, but it supports the idea that the inability to inhabit unstimulated moments can become a vulnerability. We have also removed friction from:–

  • navigating;
  • waiting;
  • remembering;
  • tolerating uncertainty;
  • performing manual calculations;
  • repairing misunderstandings;
  • and learning how something works before automating it.

Useful friction might mean:–

  • drafting the first version before asking AI to improve it;
  • sitting through ten minutes of boredom without feeding it;
  • making the phone call rather than sending six ambiguous messages;
  • walking a short journey;
  • recalling an answer before searching for it;
  • navigating occasionally without GPS;
  • learning the underlying system before outsourcing it;
  • or allowing another person time to reply without catastrophising.

The intelligent question is not: How can I make my life harder? It is:

Which capacities do I refuse to let convenience atrophy?

The BODYFIRST diagnosis: three states that look deceptively similar

  • A person resting on a sofa may be avoiding life— or recovering intelligently.
  • A person training hard may be building capacity— or accumulating an injury.
  • A person working late may be completing a meaningful surge— or borrowing heavily from tomorrow.

From the outside, the behaviours can look identical. BODYFIRST distinguishes three diagnostic states.

Protective Rest

Protective Rest is a temporary reduction in demand that preserves future capacity. Your system may be:–

  • ill;
  • injured;
  • sleep-deprived;
  • hormonally strained;
  • in pain;
  • overstimulated;
  • grieving;
  • or recovering from a significant surge.

Protective Rest is not automatically avoidance. Sometimes it is the most disciplined decision available.

The important question is whether rest is helping you return to life— or gradually becoming a bunker from it.

Useful Challenge

Useful Challenge is purposeful, appropriately dosed and recoverable. It may feel uncomfortable. But after recovery:–

  • the same task becomes more manageable;
  • strength increases;
  • confidence becomes more embodied;
  • skill improves;
  • uncertainty becomes more tolerable;
  • or your baseline expands.

This is the territory of hormesis. The challenge creates a useful adaptation rather than merely producing a dramatic experience.

Destructive Strain

Destructive Strain occurs when demand repeatedly exceeds accessible fuel, health, support or recovery. You may still perform.

High performers frequently can. The output may be financed through:–

  • adrenaline;
  • fear;
  • anger;
  • guilt;
  • urgency;
  • perfectionism;
  • or the need to prove that you are not weak.

The cost arrives later. I call this delayed billing:–

  • the trip you survived, followed by three days in bed;
  • the project you delivered, followed by a flare;
  • the meeting you powered through, followed by shutdown;
  • the workout you completed, followed by an injury;
  • the relationship you stabilised, followed by private collapse.

Your output during the surge may look impressive. The diagnostic information often appears afterwards. Ask:–

  • Did I return to baseline?
  • How long did recovery take?
  • Did the same challenge become more manageable?
  • Am I developing capacity—or demonstrating that I can override myself again?
  • Is my baseline expanding, remaining stable or quietly deteriorating?
  • Is my body adapting—or keeping receipts?

Muscles are not built because suffering is virtuous

We often hear:

Muscles are broken in the gym, fed in the kitchen and grown during rest.

The principle is directionally useful, but the biology is more precise. Resistance training challenges muscle. Mechanical tension, nutrition and recovery support adaptation. Training to complete failure is not consistently required for strength or hypertrophy, and excessive muscle damage is not proof of a superior session. A cleaner version is:

Muscles are challenged in the gym, fed in the kitchen and built during recovery.

And not everything that hurts grows muscle. Sometimes you are simply getting injured.

Apply that beyond fitness. A difficult conversation may build courage. Living in perpetual relational warfare does not. A controlled deadline may sharpen execution. Chronic urgency degrades judgement. A demanding season may develop leadership. A permanently chaotic workplace trains hypervigilance. A manageable degree of uncertainty may grow your tolerance. Years of ambiguity from someone who refuses to communicate simply drain you.

Harder is not automatically better.

Ease is part of habit architecture—not something to feel ashamed of

People often assume that if they need to design their environment around a habit, the habit somehow does not count.

They want to prove that they possess enough willpower to overcome:–

  • an inconvenient home;
  • a draining commute;
  • an impossible schedule;
  • too many accounts;
  • a headache-inducing workspace;
  • sensory overload;
  • and their own neurobiology every day.

As someone with ADHD, my kettlebells sit beside my desk. My gym is downstairs. I have very few credit cards. My investments are automated. My friends sometimes think I am nuts when I pass on a free gift, another rewards programme or even the possibility of growth above 15 per cent because I do not want the additional cognitive clutter.

I am not rejecting opportunity. I am asking whether this opportunity will create more monitoring, administration, decisions and open loops for years.

 

The real calculation is not: How much could I gain?

It is: What will this cost my head to hold?

A 2024 systematic review and meta-analysis found that health-related habits usually took considerably longer than the mythical 21 days to develop. Repetition, timing, self-selection, enjoyment and preparatory behaviours influenced habit strength, with substantial variability between individuals.

That is precisely why good architecture matters. Put your medication where you see it. Lay out your training clothes. Use the beautiful water bottle. Keep nourishing food accessible. Automate saving and investing. Move the distracting app away from your home screen. Choose the gym you will actually enter— not the magnificent one requiring a forty-minute act of heroism. Use the supportive shoes. Work in the room where your nervous system settles.

Feng shui, interior architecture, environmental psychology, sensory ergonomics, biophilic design and choice architecture arise from different traditions. They are not scientifically interchangeable. They do, however, share a useful question:

How is the environment shaping the person inside it?

A systematic review of workplace nature exposure and biophilic environments found promising restorative effects on well-being, motivation, satisfaction and performance, while also noting that the evidence base remains limited and heterogeneous. Why would you voluntarily live or work somewhere that gives you a headache, strains your senses and depletes your battery— then call the daily battle discipline?

If ease helps you repeat what is good for you, ease is part of the training.

Ask what the ease is compounding

Ease becomes dangerous when it compounds:–

  • passivity;
  • avoidance;
  • impulsive consumption;
  • dependency;
  • numbness;
  • deconditioning;
  • or the inability to tolerate ordinary life.

Ease becomes intelligent when it compounds:–

  • health;
  • financial stability;
  • learning;
  • strength;
  • connection;
  • creative output;
  • recovery;
  • or peace.

A standing investment instruction may make wealth easier to compound. A kettlebell beside your desk may make strength easier to compound. A pre-written grocery list may make nourishment easier to repeat. A tidy room may reduce enough friction for you to begin. A trainer may provide enough structure for you to exercise consistently and safely.

The ease is not the weakness. The outcome it repeatedly produces is the answer.

Choose the resistance you train

Lean muscle is protective.

It supports mobility, metabolic health, independence and the ability to recover from illness or injury. From around age 30, adults typically begin losing muscle mass, with NIH estimating an average decline of roughly 3–5 per cent per decade. The rate and functional consequences vary considerably between people.

Women also contend with musculoskeletal changes around menopause.

Dr Vonda Wright and colleagues introduced the term musculoskeletal syndrome of menopause to describe a cluster that may include joint pain, loss of muscle and bone, tendon and ligament problems, cartilage changes and progression of osteoarthritis in the context of declining oestrogen. It remains a proposed clinical framing rather than a universally standardised diagnosis, but it usefully draws attention to a neglected area of women’s health.

So yes, I lift my kettlebells sensibly. I hop onto my trampoline because it is close, enjoyable and therefore repeatable. Structured jump-training studies suggest modest, skeletal-site-specific benefits for bone mineral density in adults. But a recreational trampoline routine is not identical to a supervised research protocol, and impact exercise is not appropriate for every joint, pelvic floor or osteoporosis profile.

I am not trying to annihilate myself in the name of fitness. I am introducing enough resistance to preserve future options.

Now extend that logic into career and life. Useful resistance may mean:–

  • telling someone no while tolerating the possibility that they judge you;
  • allowing another capable adult to solve the problem they created;
  • presenting before every sentence is perfect;
  • taking ownership before you can tick 150 per cent of the boxes;
  • hearing feedback without immediately defending yourself;
  • sitting inside the uncertain gap between effort and result;
  • beginning the first draft without AI;
  • or having the conversation you have rehearsed internally for six months.

Sometimes a better script is enough. Sometimes you need to go deeper.

Why does disapproval feel catastrophic? Why do you interpret another person’s disappointment as evidence that you have done something wrong? Why does the possibility of abandonment make self-abandonment seem reasonable?

Then you build a strategy. You practise a different response. You repeatedly teach your body that dignity does not equal desertion.

That takes courage. That takes discipline. That takes devotion. Continuing the same loop because you are “nice” does not.

What are you tolerating— and why?

Every yes you utter when you really mean no creates a private entry in the ledger.

You tell yourself: It is only five minutes. I can do it faster. They need me. I do not want to look difficult. No one else will do it properly. One resentful yes may be trivial. A lifestyle constructed from them compounds— not at the sedate rate of a diversified ETF, but at alarming loanshark rates.

The interest is paid through:–

  • irritation;
  • vigilance;
  • emotional clean-up;
  • unfinished priorities;
  • bodily tension;
  • poor sleep;
  • and the growing belief that your life belongs to everyone except you.

To be scientifically precise, one unwanted favour does not produce inflammation or cause autoimmune disease. But chronic physiological strain is not biologically neutral.

A systematic review covering 267 investigations found that higher allostatic load— the cumulative multisystem burden associated with adapting to chronic stress and life events— was associated with poorer physical and mental-health outcomes.

A large Swedish cohort study also found that people diagnosed with stress-related disorders had higher subsequent rates of autoimmune disease than matched unexposed individuals and their siblings. That association does not prove that stress directly caused the diseases, but it is enough to reject the fantasy that repeated severe strain is free.

Stop pretending repeated self-abandonment carries no biological cost.

Are you tolerating your tolerating?

High-performing women are especially prone to converting overfunctioning into identity. You martyr yourself. You rescue everyone. You keep up the slack. You clean the mess. You decide nobody else can be trusted to do it properly. Then, because you repeatedly protect other adults from the consequences of their inaction, they never develop the capability you insist they lack.

That is not always excellence. Sometimes it is enabling with exceptional project management.

The more you rehearse being indispensable, the more imprisoned you feel inside the role. Your environment then reflects the operating system you keep renewing:–

  • more gaps appear for you to fill;
  • more people expect rescuing;
  • more evidence emerges that nobody considers your capacity;
  • and your competence becomes the reason everyone gives you more.

Here is the tough DrP love. Before awareness, this may have been conditioning, fear or an old survival strategy. Once you see the dynamic clearly, awareness changes the contract. If you repeatedly continue the pattern unchanged, you are no longer only trapped inside it. You are helping to renew it.

You asked for the extension— not because you deserved the original burden, but because you keep signing the renewal.

That is accountability at the highest order. Knowing you asked for it.

When something stirs in you but your body cannot immediately fund it

Something stirs in you. A larger business. Motherhood. A new career. A physical comeback. A different relationship. More travel. A richer life. Or perimenopause arrives and makes it increasingly difficult to keep lying about what your body needs.

The immature response is to push harder. The defeatist response is to shrink the desire. The BODYFIRST response is:

Build the infrastructure that makes the next chapter possible.

Ask:–

  • What capacity must I build?
  • What friction must I remove?
  • What fuel must I restore?
  • What support must I introduce?
  • What can be seasonal rather than permanent?
  • Which ambiguity must I learn to engage with?
  • Which ambiguity is simply bad design?
  • What am I currently financing with adrenaline?
  • What will the delayed crash cost?
  • Which parts of my body and life must become stronger for the long game?

And for anyone saying they have become soft compared with their twenties, here is the honest correction.

Your body now has a longer history. It may be carrying:–

  • accumulated sleep debt;
  • previous injuries;
  • chronic pain;
  • hormonal shifts;
  • medication effects;
  • illness;
  • deconditioning;
  • entrenched habits;
  • prolonged stress exposure;
  • more responsibilities;
  • and fewer recovery buffers.

There is no need to use the scientifically vague language of “toxins” to make the point. You have not necessarily become weak. You are commanding a system with more accumulated data and less tolerance for dishonest accounting. That demands a more sophisticated strategy.

Play the long game with the body and brain you expect to inhabit

Many of us are preparing for lives that may extend towards 100. Longevity without function, however, is merely a longer exposure window.

WHO estimated that the number of people living with dementia could rise to 139 million by 2050. A Global Burden of Disease forecasting analysis produced a higher estimate of approximately 153 million. Forecasts vary, but they agree on the direction: population growth and ageing will create an enormous global burden.

This does not mean every moment of stress is damaging your brain.

The relationship between anxiety and dementia is more complex than many wellness headlines suggest. A 2022 systematic review and meta-analysis of longitudinal studies found no clear overall association between anxiety disorders and subsequent dementia, although the evidence was limited and mixed. Other analyses have found associations in particular groups, including people already experiencing subjective cognitive decline. Anxiety deserves treatment because it affects life now—not because scare content can promise a simple causal line to dementia later.

Hearing belongs in the long game too. A recent meta-analysis of cohort studies using audiometrically measured hearing loss found an association with a higher incidence of dementia. That does not prove a simple direct causal pathway, but it adds to a substantial body of evidence linking hearing and cognitive health.

WHO estimates that more than one billion people aged 12–35 are at risk of preventable hearing damage through unsafe recreational sound exposure.

The problem is not the moral existence of headphones. It is volume multiplied by duration.

Protect the systems you expect to inhabit for those additional decades:–

  • muscle;
  • bone;
  • hearing;
  • sleep;
  • cardiovascular capacity;
  • cognition;
  • digestion;
  • curiosity;
  • and human relationships.

That is worthwhile friction.

Beauty, pleasure and comfort can be performance inputs

Some comforts make you smaller. Others restore enough dignity, safety and energy for you to participate in life. The difference matters.

As someone who lives with chronic fatigue and fibromyalgia— and who has experienced around 40 fevers a year since childhood— I can tell you that my beauty rituals saved my life.

That is no exaggeration.

Growing up, I watched my mother, who lives with similar pain and fatigue, put on a beautiful dress. Her mood lifted. She held her head higher. She went out and smiled. She returned feeling more purposeful.

If the dress is the button that changes your state, it is not vapid. It is amazing.

Clothing affects how people are perceived in workplaces. A 2024 integrative review concluded that characteristics such as formality and fashionability can influence observers’ judgements of warmth and competence, although these effects vary by person, culture and context.

Appearance bias also exists, but the familiar claim that beautiful people straightforwardly earn substantially more requires caution. A meta-analysis of 1,159 estimates found a mean reported association between beauty and earnings or productivity. However, publication-bias corrections reduced the apparent premium, and controlling for cognitive ability brought much of the remaining effect towards zero. Beauty affects perception; a large causal earnings premium is far less secure than popular headlines imply.

So the honest conclusion is not: Become beautiful and you will earn more.

It is:

People make biased judgements from appearance— and your own experience of your appearance can change how you inhabit the day.

If putting on a beautiful dress helps you stand taller, leave the house, train, speak, connect or begin again, it is a legitimate state-shifter.

If vanity is the dubious springboard that gets you into the gym, start there. We can refine the motive later.

We cross continents to look at mountains, gardens, architecture and oceans. We arrange flowers. We preserve paintings. We photograph the sky.

Let us not pretend beauty suddenly becomes morally suspicious when the landscape is your own body. Ask of every comfort:–

  • Does this replenish me or numb me?
  • Does it make me more available for life— or less?
  • Does it help me return to myself?
  • Does it compound health, connection, courage or joy?
  • Or does it gradually narrow the range of life I can tolerate?

The BODYFIRST Friction Audit

Before making anything harder, sort your life into four categories.

1. What should become easier?

What do you want to compound? Perhaps:–

  • strength;
  • nourishing meals;
  • sleep;
  • medication adherence;
  • saving and investing;
  • deep work;
  • learning;
  • creativity;
  • closing administrative loops;
  • contacting people you love;
  • recovery.

Remove friction here.

2. What should become harder?

What reliably destabilises or diminishes you? Perhaps:–

  • impulsive spending;
  • doomscrolling;
  • contacting someone who repeatedly dysregulates you;
  • agreeing to meetings without agendas;
  • buying another shiny protocol;
  • eating purely from agitation;
  • saying yes automatically.

Add a pause, password, physical barrier, spending rule or decision window.

3. What should you practise tolerating?

Which discomfort produces a capacity you genuinely need? Perhaps:–

  • receiving feedback;
  • uncertainty between effort and result;
  • saying no;
  • allowing someone to be disappointed;
  • progressive physical training;
  • beginning before you feel perfectly ready;
  • having a direct but dignified conversation;
  • completing the first draft before asking AI.

Dose it. Recover. Repeat.

4. What should you stop tolerating?

Which strain is shrinking your baseline? Perhaps:–

  • chronic sleep deprivation;
  • recurring disrespect;
  • untreated pain;
  • preventable sensory overload;
  • chaotic collaborators;
  • endless relational ambiguity;
  • repeatedly rescuing adults from their own decisions;
  • an identity built around being the only competent person in the room.

Then apply three time windows.

  • Short term. What does this cost or provide today?
  • Medium term. What habit, physiological response or identity is this rehearsing?
  • Long term. What will this compound into over five, ten or thirty years?

What are you compounding?

The final question is not: Was this easy or difficult? It is:

What am I compounding here?

Tangible dividends may include:–

  • muscle and bone;
  • healthspan;
  • hearing;
  • financial assets;
  • career capital;
  • practical skill;
  • reliable habits;
  • fewer rework loops;
  • time recovered from preventable crises;
  • an environment that supports action;
  • reciprocal relationships.

Intangible dividends may include:–

  • joy;
  • awe;
  • curiosity;
  • courage;
  • self-trust;
  • dignity;
  • discernment;
  • peace;
  • tolerance for meaningful uncertainty;
  • freedom from unnecessary suffering.

Perhaps the easy route compounds wealth because automation prevents you from interrupting your investments. Perhaps the harder route compounds skill because writing the first draft yourself preserves your thinking. Perhaps the pleasurable route compounds health because you actually repeat it.

Perhaps the difficult relationship is not building resilience. Perhaps it is merely building tolerance for being treated badly.

Perhaps what you call laziness is Protective Rest. Perhaps what you call discipline is fear. Perhaps what you call comfort is the environment your body needed all along.

Controlled Command: select the difficulty

High performance is not the ability to tolerate maximum friction. It is Controlled Command:–

  • Choose the challenge that matters.
  • Commit enough energy for adaptation.
  • Correct when the dose, timing or context is wrong.

You do not need a frictionless life.

You need a life in which friction is selected rather than inherited, designed rather than chaotic and useful rather than theatrical.

When your performance currently depends on borrowed energy, the answer is not another discipline hack.

It is a better diagnosis.

A Strategic Session maps your BODYFIRST profile:–

  • baseline;
  • surge;
  • borrowed energy;
  • delayed crash;
  • recovery;
  • true expansion;
  • overstimulation;
  • environmental support;
  • and the difference between a limit to respect and a capacity to build.

From there, we identify which friction to remove, which resistance to train and what your body can realistically fund in the next chapter.

Make the good easier. Make the harmful harder. Train the discomfort that enlarges your life. Stop worshipping the discomfort that merely consumes it. Start getting strategic here, limited slots monthly.

Frequently Asked Questions

  • What is friction-maxxing? Friction-maxxing is the intentional introduction of inconvenience, effort or delay into daily life to counter excessive convenience and preserve capacities such as patience, attention, competence and tolerance for discomfort.
  • Is friction-maxxing good for you? It can be useful when the challenge is purposeful, appropriately dosed and followed by recovery. It becomes harmful when it creates injury, depletion, needless risk or a declining baseline.
  • What is the difference between hormesis and destructive stress? Hormesis is an adaptive response to a manageable dose of challenge. Destructive stress exceeds the person’s current capacity or recovery and leads to deterioration rather than expansion.
  • How do I know whether discomfort is helping me grow? Look beyond whether you completed the task. Assess whether you recovered, returned to baseline, became more capable and found the same challenge more manageable over time.
  • When should I make a habit easier? Make a habit easier when repeating it produces a long-term dividend such as strength, health, learning, financial stability, connection or peace.
  • What is Protective Rest? Protective Rest is a temporary reduction in demand because the body or brain is depleted, ill, injured, hormonally strained or overstimulated. Its purpose is to preserve or restore future capacity.
  • What is Destructive Strain? Destructive Strain occurs when demands repeatedly exceed accessible fuel, support or recovery. A person may continue performing through adrenaline or self-override, but their delayed crash worsens and baseline capacity declines.
  • What is BODYFIRST? BODYFIRST is DrP’s biology-aware framework for interpreting signals from the body, brain, gut and environment before deciding what kind of challenge, rest or redesign is needed.
