When Working Harder and Faster Stops Working

I have been having the same conversation, in different rooms, for years now.

The room changes. The industry changes. The titles on the door change. Private Equity. Law. Music. Tech. Founders. Operators. Partners. But the conversation is roughly the same.

A high-performing leader sits across from me. They have built a career on a particular operating system. Long hours. High intensity. A relentless inner voice that pushes them forward. It worked. For decades, it worked.

And then, somewhere in their forties or fifties, occasionally earlier, the operating system stops working.

The inputs go up. The outputs go down. The recovery time stretches. The decisions get cloudier. They notice they are reactive in ways they did not used to be. And the response, almost always, is the same one that built the career in the first place. Push harder. Sleep less. Drink more coffee. Outwork the problem.

It does not work.

I want to share why, drawing on the work of one of the most quietly important psychologists of our time. Professor Paul Gilbert OBE has spent more than forty years asking a single question. Why are humans, who are clever enough to put rockets into space, so cruel to themselves? The answer became Compassion Focused Therapy, now used worldwide for depression, anxiety, burnout and self-criticism.

What follows is a fraction of what is in the book. If anything here lands, read it.

Three systems running underneath everything

Gilbert's most useful idea is that our emotional life is shaped by three systems.

The first is the threat system. It protects you from danger. It brings anxiety, anger, the feeling of needing to brace. Useful, but exhausting if it is always on.

The second is the drive system. It pushes you to chase, achieve, win, tick things off. It brings excitement, the buzz of progress, the urge for more. Useful, but hollow on its own.

The third is the soothing system. It lets you rest, connect, feel safe with people, feel content. It brings warmth, calm, ease. Often the quietest one. For most high performers, it has been almost silent for years.

Most successful people have one or two systems running too hot, and the third quietly buried.

The paradox almost no one notices

Here is the bit that catches almost everyone off guard.

The soothing system is not the opposite of high performance. It is the foundation of it.

When the threat system is running, your body is flooded with cortisol. The prefrontal cortex, the part of the brain you actually need for creative thinking and good judgement, runs at reduced capacity. You can grind. But you cannot think well. The brain only consolidates new learning and recovers properly when the soothing system is online.

The growth you are scared of missing by resting is the exact growth you are missing by not resting. Push a depleted system and it gets less productive, not more. We have just been trained to mistake the busyness of pushing for the productivity it used to deliver.

Three patterns we see again and again

If one of these is a mirror, that is useful information.

The always-on operator. A decade or two of eighty-hour weeks. Treats sleep, exercise, and recovery as buffer to be sacrificed. Cortisol up, HRV (Heart Rate Variability) down, decision quality slipping. Cannot quite see it from the inside. Believes the engine that built the career is the engine that will sustain it. Begins to track recovery as seriously as performance only when something gives way. The realisation is always the same. Output has been declining for years, and effort has been masking it.

The bottleneck. Smartest person in the room. Holds it all. Cannot delegate without a low hum of anxiety. Quietly believes nobody else will get it right. Everything moves at the speed of one head. The team senses the mistrust and pulls back. The shift, when it comes, is realising that the inability to receive support is not a strength. It is a specific failure mode. Lets a senior colleague carry something end to end. The team rises. The bottleneck, it turns out, was always at the top.

The brutal coach. Never satisfied. The inner voice that drove the early wins has become indiscriminate and corrosive. Talks to themselves the way they would never talk to a junior member of their team. Confuses cruelty with rigour. Mistakes shame for accountability. The shift is noticing the gap between how they coach others and how they coach themselves. Standards stay high. The cruelty stops. The team feels the difference within weeks.

If those patterns ring familiar, the check below tends to confirm it.

A useful question

Here is something I ask clients when they cannot quite see it from the inside.

Imagine your nervous system as a 10-year-old child you love. How would you feed them? When would you put them to bed? How much screen time would you allow? What would you say to them when they were struggling?

Would you let them drink six coffees and stay up until midnight, working? Would you shout at them when they made a mistake? Would you tell them they should be doing more?

That child is what most of us have been ignoring for a very long time. Looking after them is not soft. It is the most strategically important thing you can do.

The foundations

Before any clever protocol, the basics. No breathing exercise will save a system that is being malnourished, dehydrated, sleep-deprived, and chemically agitated.

Sleep. Seven to nine hours, consistent timing. The brain consolidates learning and clears metabolic waste during sleep. Below seven hours, decision-making, emotional regulation, and risk perception all measurably degrade.

Hydration. Two to three litres of water a day. Most high performers run mildly dehydrated all day because they are running on coffee. Coffee is not water. Drink a glass of water before every coffee.

Food. Real food. Protein at every meal. Skipping meals to push through and eating processed food on planes is a tax that compounds. The body keeps the score.

Caffeine. Half-life of around five to six hours. The 4pm coffee is still actively in your system at midnight, fragmenting your sleep architecture. Cut caffeine after 2pm.

Alcohol. Alcohol does not help you sleep. It sedates you, then shreds your REM sleep in the second half of the night. Even moderate evening drinking elevates resting heart rate and lowers heart rate variability. If you drink, do it earlier and less often than you think.

When the brain says X, what helps is Y

Once the foundations are in place, the inner voice becomes the next leverage point.

When the brain says "If I rest now, I will lose my edge", what helps is "I lose my edge faster grinding through depletion."

When the brain says "I should be able to handle this on my own", what helps is "Strong people ask for help earlier, not later."

When the brain says "If I am not producing, who am I?", what helps is "The people who love me have never measured me by my output."

When the brain says "I do not have time for any of this", what helps is "I do not have time not to."

These are small. They are also the most well-evidenced way to interrupt the threat loop in the moment.

The thing the protocols cannot do alone

Here is the bit that almost no one in the productivity literature mentions.

T

he soothing system did not evolve through solo meditation. It evolved through mammalian bonding. Babies regulating with mothers. Pack animals lying together. The earliest version of safety was always another nervous system telling yours that things were alright. The technical term is co-regulation. It is the reason a five-minute conversation with the right person can do what an hour of solo breathing cannot.

This is why animals lower cortisol and raise oxytocin within minutes. Why a real conversation with someone who knew you before you were impressive can put you back in touch with a version of yourself that was not braced. Why therapy and coaching, done well, work. The reason they work is not primarily the insights. It is the hour spent in a regulated relational field, repeated over months. Insight is a side effect. The relationship is the medicine.

The soothing system is not a private gym you go to alone. It is rebuilt in relationship.

A closing thought

Aim for around 15 percent of your day in deliberate soothing mode. Roughly one and a half to two waking hours. Most high performers run at less than 5 percent. The gap is where the burnout lives, and where the productivity quietly leaks.

If only one sentence stays with you, let it be Gilbert's

Paul Gilbert's theory

The work is not to push harder. The work is to bring something back online that has been quiet for years.

If any of this is recognisable to you, or to someone in your team, I would love to hear about it. The conversation I described at the start of this piece is the one I have most often. It is also the one most worth having early.

5 Key Takeaways

• High performance often runs on two overactive systems — threat and drive — while the soothing system (rest, connection, calm) becomes neglected, eventually reducing clarity, resilience, and decision quality.

• Rest and recovery are not the opposite of productivity; they are essential for cognitive performance, creativity, learning, and sustainable leadership.

• Many senior leaders fall into recurring patterns: the always-on operator, the bottleneck who cannot delegate, and the brutal inner critic who mistakes self-criticism for high standards.

• Sustainable performance starts with foundational habits — sleep, hydration, nutrition, reduced caffeine/alcohol, and nervous system regulation — before any advanced “optimisation” techniques.

• Human connection and co-regulation are critical to recovery and wellbeing; the soothing system is rebuilt through safe relationships, support, conversation, coaching, and community — not through isolated self-improvement alone.
