The One Behaviour That Works Every Time
“Repetition is the source code of excellence.”
\- Steven Kotler
I’m in the process of onboarding a new CEO client and when we spoke about aspects of his current routine he described it in a tone, bordering on the apologetic, as boring.
What I actually saw was discipline. And in 2026, discipline has become so rare that people mistake it for a personality flaw.
What I See in Every Great Leader
I've spent a significant portion of my career working with executives, entrepreneurs and founders across multiple industries and geographies. Different cultures, different worlds, different challenges.
But there is one trait I see in every genuinely excellent leader, without exception.
They know the value of discipline.
A piece of research I frequently reference is the Mundanity of Excellence - a study of competitive swimmers by sociologist Daniel Chambliss. The research set out to identify what actually separates the best from the rest.
Talent played a part, of course, but at a certain level that wasn’t enough. The distinguishing factor became the willingness to stay intentional and purposeful in the face of the unglamorous work.
The same drills, repeated with precision. The same early mornings, the same discipline around sleep and nutrition. None of it glamorous. But all of it compounding over time.
What looks like extraordinary performance from the outside is almost always the result of ordinary behaviours, executed extraordinarily well, over a very long time.
That principle applies in every domain. And it applies to leadership more than most people acknowledge.
What Neuroscience Tells Us
Every time you repeat a skill with focused intention, you reinforce the myelin sheath around the relevant neural pathways. Myelin is the fatty tissue that wraps nerve fibres - and the thicker it gets, the faster and more precise your neural signals become.
This process, myelination, is how deliberate repetition rewires the brain. It is the biological mechanism that leads to mastery.
The key word here is deliberate. Intentional repetition, where the prefrontal cortex is engaged and where you are focused on quality and refinement, is what creates mastery. The brain does not respond solely to volume. It responds to quality of attention.
That last point is critical for me, because even though I have always had a strong pursuit of personal development, I know that for a significant part of my time in leadership, my learning curve was primarily through osmosis. It also involved big chunks of time spent operating on ‘auto-pilot’ - getting stuff done, fighting fires and lost in pursuit of productivity. It meant I didn’t build in periods of reflection on my performance and I wasn’t consistent regarding my growth potential.
When I look back now, I think of my progress as like sailing without sat nav. I was heading in the right direction, but had to make plenty of course corrections and lost a lot of time.
The Elite Know The Reality
I spent more time this week with Kevin O'Connor, the former Special Forces Team Leader, exploring the lessons corporate leaders can learn from the toughest arenas of all.
Kevin was in the Special Reconnaissance Regiment and most people assume that line of work is high-octane and constantly dramatic. In reality, a significant proportion of it is surveillance, intelligence gathering and, given the stakes, an incredible attention to detail. Preparation and work that is a world away from the Hollywood version and that to some would be deeply boring.
Crucially, that disciplined preparation is precisely why they are able to perform when it matters. The unglamorous work done in the shadows is what makes the high-stakes moments look effortless.
It's no different in business.
What This Means As A Leader
It’s clear that mastery requires willingness to tolerate mundanity. But given my obsession with executive performance, I also want to talk about the dimension of this that rarely gets talked about.
The discipline to maintain consistency in values and behaviours isn't just a personal performance asset. It is one of the most powerful things you can do for the people around you.
When your team knows exactly what you stand for and exactly what standard is expected of them, that creates psychological safety.
That phrase is thrown around a lot, but I don’t mean in some ‘woo woo’ way, I actually mean in the neurological sense. The brain is a prediction machine; it is constantly scanning for patterns, for threat, for certainty. A leader who is consistent removes an enormous amount of cognitive noise from the environment. It means your team can direct their energy into the work rather than into reading the room, second-guessing, managing up etc.
You know what I’m talking about, because you’ve been there, right?
In a world that far too frequently champions performative nonsense, understand this fact: the leaders who command the deepest loyalty and the best performance from their teams are not always the most charismatic, or the most visionary. They are frequently the most predictable… in the very best sense of that word.
That requires discipline.
So stay the course. Be selective about who you take advice from - a lot of people are selling maps to places they've never been. They haven’t survived storms. They haven’t had to look after a crew.
A word of warning, though. Discipline in values and behaviours is not the same as bloody-mindedness. I've seen leaders confuse the two, and it costs them. The objective doesn't change. The standards don't change. But the route frequently will. Conditions are like the weather, constantly shifting and not always in a predictable way. The adaptive leader adjusts the path when the evidence demands it, without abandoning where they're headed or who they are in the process.
Hold the Horizon
One of the things I took a long time to grasp about leadership is that you control far less than you think. The sooner you make peace with that, the better a leader you become.
You can't control the weather. The best captains read it, adjust their heading, and keep the ship moving. The conditions change constantly. The destination doesn't.
When everything is shifting, your job is to hold the horizon steady. For yourself. For your team.
That requires discipline.
PS. The client I mentioned at the start? All substance, no flash, powered by a genuine curiosity about how he can show up better, in role and in life. That’s the type of talent it’s a privilege to work with.
🔥 LIVE BETTER, LEAD BETTER
The best content I researched this week:
1. Is flip-flopping ever good? Tying in directly with this week’s theme, this thought-provoking article explains that while leaders fear changing course will undermine their credibility, done the right way it actually inspires confidence.
2. However, when making decisions, it's easy to confuse instinct and intuition and that can lead you to choosing the wrong course. Hence I’m a big fan of this Gut Decision Matrix drawn up by neuroscientist Anne-Laure Le Cunff.
3. Distraction is also detrimental to decision-making, so, here are 3 simple steps to breaking your phone addiction from entrepreneur and author Sahil Bloom (I’m trying this myself so will keep you posted).
4. And finally, to wrap things up perfectly, a 65-second video on the importance of knowing whose opinion you should listen to from Finding Mastery host Dr Michael Gervais.
