The efficiency of the exhausted

Posted on: 2 May 2026

I woke up without an alarm this morning and had an unwelcome thought: most of the strategic errors I have witnessed in forty years of work were not made by people who worked too little. They were made by extremely intelligent people who worked all the time. Partners who never switched off, founders running on five hours of sleep, directors answering emails at eleven at night with the same precision they brought to nine in the morning. Disciplined, focused, tireless. And making the same mistake, repeatedly.

The mistake was not laziness, obviously. It was a very specific form of blindness: seeing the present through the lens of the recent past, becoming superb at executing yesterday's playbook while the world quietly changed the question. In the years when we were digitising cinema distribution across an entire country, I watched extraordinary executives optimise the physical distribution chain with surgical attention while Netflix was rewriting what distribution actually meant. They were not stupid, none of us were. We were tired in the way that does not show from the outside: tired of patterns, not of muscles.

For a long time I thought this was a question of mental flexibility, of individual capacity to read weak signals. Then I started looking at it from the neurobiological side and realised I was looking at a structural phenomenon, not a character flaw. The human brain has a system designed precisely to do what continuous work prevents it from doing. It is called the default mode network and it activates the moment we stop concentrating on a specific task. It is not idleness in disguise, nor inefficiency tolerated by evolution. It is the system through which we consolidate patterns, recombine information, and recognise connections that simply do not emerge inside narrow focus. Suppressing it chronically does not produce more productive people. It produces people who are faster at executing patterns they already know, and blinder to patterns they do not.

Here lies the twist that hustle culture cannot afford to tell, because telling it would dismantle the entire premise. Working all the time does not accumulate competitive advantage; it accumulates cognitive inertia. It makes people excellent at a craft the world is quietly ceasing to demand, while convincing them they are more dedicated than the competition. And it is precisely their dedication that is the problem, because it forecloses the step back that would allow them to notice the craft has shifted underneath them.

The City tells this story particularly well, though it tells it in code. Every cycle, the same pattern: a generation of professionals built on relentless availability discovers, somewhere between forty-five and fifty, that the deals they are excellent at structuring are not the deals the market now wants. Northern Rock was not undone by people who underworked the risk; it was undone by people who had been so continuously present that they had stopped asking the question. The Chilcot inquiry, in its quiet methodical prose, kept circling the same observation about the run-up to Iraq: not absence of work, but absence of pause. Decisions made by exhausted people, in rooms where exhaustion had become a proxy for seriousness.

There is a detail worth examining clinically: who actually profits from the narrative of hustle as virtue? Not, as a rule, those who produce results, certainly not in proportion to the rhetoric. The profits accrue to the platforms that monetise continuous attention, to the publishers of motivational content selling progressively tighter discipline, to the training operators offering courses on sleeping less and producing more. The hustle narrative is economic infrastructure for other people, not a personal strategy. Those who embrace it most enthusiastically are building someone else's capital while eroding their own.

Look at chess at the highest level. Magnus Carlsen and the players of his generation have built their preparation around recovery cycles as aggressive as the study cycles, not for reasons of wellness but because anyone who fails to rest loses in the positions that require positional creativity, which are precisely the ones that decide tournaments. Jazz works the same way: the great improvisers do not always play. They alternate periods of intense practice with periods of listening, of silence, of apparent inactivity during which the brain reprocesses. Coltrane stopped for months before A Love Supreme. This is not biographical colour, it is the mechanism. Endurance sport has known this for decades: elite athletes do not train continuously, they periodise. Those who fail to periodise either get injured or stop improving. Everyone knows this except, curiously, people who work in offices.

The point becomes more uncomfortable, however, and I want to be clinical about it. Working all the time is not merely counterproductive. It is, on occasion, a highly sophisticated form of avoidance. One works continuously in order not to face the difficult question, which is: am I working on the right things? Real focus, the kind that produces results, requires recovery precisely because it requires returning to the work and seeing it from outside. Those who never come back from outside never see from outside. They cannot correct course; they can only accelerate in the direction they chose three or four years ago, hoping it was the right one. Continuous motion conceals absence of direction better than anything else, because it has all the appearances of rigour.

I know this trap intimately, because the trajectory is always the same and I have watched it function on very different people, including, some time ago, on myself. It presents as dedication, lives as duty, produces apparent results for somewhere between five and ten years, and then something breaks. Not always dramatically. Sometimes the firm simply loses relevance, the product ages, the market shifts, and the person who worked all the time finds themselves unable to understand why all that effort failed to produce the expected advantage. The clinically honest answer is that the effort had become the objective, while the stated objective had become an alibi for not stopping the effort.

Pleasure, in this frame, is neither reward nor compensation nor wellness. It is an instrument of reality testing. It is the moment in which the nervous system returns information about how you are actually using your time, what you are actually building, how connected the work you do is with the person you mean to become. Anyone who has stopped feeling pleasure has lost a critical informational channel, not a secondary benefit. And by pleasure I mean the kind that requires unmonetised time: a long lunch, a walk without a podcast, a morning without objectives, a conversation that goes nowhere. All things that productivity culture has reclassified as wasted time, when they are in fact the system through which the brain performs the maintenance required for high-level pattern recognition.

There is a simple test for whether the argument holds. Look at the people around you who have been visibly tireless for at least five years and ask yourself: how many of them have produced a significant strategic insight in the last twelve months, something that was not an incremental variation on what they were already doing? How many have changed their mind about something important, on the basis of evidence that forced them to see their field differently? If the answer tends towards zero, you have empirical confirmation of the mechanism. Working all the time does not lead to seeing more things; it leads to seeing the same things with greater executive efficiency. It is the opposite of long-term competitive advantage.

I am not making the case for laziness, to be clear. I am making the case for focus, which is precisely the opposite of what hustle culture sells under the same name. Real focus is alternation between maximum concentration and genuine recovery, because only this alternation allows the brain to consolidate what it has learned and to notice what it has not yet learned. Those permanently switched on are not focused; they are simply exhausted in a way that disguises itself as discipline. The difference shows up over long horizons. The genuinely focused produce one significant strategic insight every two or three years; the tireless produce a constant volume of output that ages rapidly.

There is something I tend to say to the few entrepreneurs I genuinely work with, and it bears repeating here. Saturday is not the day on which you do not work. Saturday is the day on which your brain does the work the week prevented it from doing, namely working out whether the week made sense. If you cancel Saturday in order to anticipate Monday, you are not gaining a day of work; you are losing five, because you are eliminating the system through which you check whether you are working on the right things. It looks productive in the short term and it produces obsolete strategies in the medium one with mechanical reliability.

In my view, the next frontier of competitive advantage in cognitive professions will not be those who work more, but those who periodise better. Those who know when to push hard and when to genuinely stop. Those who treat pleasure as a working instrument rather than a distraction from work. It is counter-intuitive only on the surface, because elite athletes, elite musicians and elite chess players have known this for decades. The cognitive professions are simply late, and they are paying for it, even if they fail to notice because everyone is paying together and therefore no one appears to be at a relative disadvantage.

I woke up without an alarm this morning and had an unwelcome thought, though not really that unwelcome, because I have had it for a while. Perhaps the genuine contemporary luxury is not free time. It is being able to recognise that the free time was not free at all. It was the time when the real work was happening, in a form the current system cannot measure and has therefore decided to call idleness.
