For high achievers, pushing harder can become a way of life. You wake up thinking about what needs to get done. You move from responsibility to responsibility. You bring work energy home. Even when you finally have a chance to rest, part of you is still switched on.

Boardroom Strategist and Creator of Ultra States Examining How Humans Actually Perform Under Pressure
30+ years Boardroom advisory experience330+ Boards advised or served on6 World’s highest mountains climbedTEDx speaker TEDxUniversityofEdinburgh
Deri Llewellyn-Davies grew up in a small rural village in Wales, where community wasn’t a concept, it was how life worked. That early sense of shared responsibility shaped how he later approached leadership, decision-making, and pressure, long before he entered boardrooms and high-stakes environments. Over three decades, Deri has advised and sat on more than 330 boards, becoming known for spotting the real constraint beneath the noise and helping organisations think clearly when the stakes are high. His signature Strategy on a Page methodology is a no 1 best seller and has inspired thousands of founders to scale with purpose.
Outside business, Deri has spent years testing human limits in extreme environments — climbing six of the world’s highest mountains, completing the Marathon des Sables, and racing the infamous Ironman. Those experiences became a lab for understanding how people actually perform under pressure, and why so many high-achievers quietly collapse when the adrenaline wears off.
That intersection of boardroom pattern recognition and extreme performance thinking led to the creation of Ultra States, a framework that reframes performance as state selection rather than motivation. Instead of treating focus, flow, connection, recovery, and peak intensity as accidents or personality traits, Ultra States examines them as distinct neurological and physiological conditions, each with trade-offs when misused or overextended.
In this episode of Rewiring Health, I’m joined byDeri Llewellyn-Daviesfor a powerful conversation about performance, burnout, purpose, fear, recovery, and what it really takes to live well when you’re wired to achieve.
Deri grew up in a small rural village in Wales, where community and shared responsibility were simply part of how life worked. That early foundation shaped the way he later approached leadership, pressure, and decision-making.Over the past three decades, Deri has advised and sat on more than 330 boards, becoming known for identifying the real constraint beneath the noise and helping founders and organizations think more clearly when the stakes are high. His signature Strategy on a Page methodology became a number-one bestseller and has helped thousands of founders scale with greater clarity and purpose.
But Deri’s understanding of performance didn’t come only from the boardroom.
He has also spent years testing the limits of human performance in extreme environments—climbing six of the world’s highest mountains, completing the Marathon des Sables, racing Ironman, and facing moments where survival itself was uncertain.
Those experiences became a kind of laboratory for understanding what happens to the mind and body under pressure—and why some of the same traits that help high achievers succeed can eventually become the very things that exhaust them.
That intersection of leadership, extreme performance, neuroscience, and lived experience led Deri to create Ultra States, a framework built around a simple but powerful idea:
You are always in a state.
The question is whether you chose it.
Through Ultra States, Deri explores the distinct states of focus, flow, connection, recovery, and peak performance and why sustainable success depends less on forcing yourself to perform constantly and more on learning how to move intentionally between them.
In this conversation, we explore:
-Why ambition itself isn’t necessarily the problemThe difference between pushing from purpose and pushing from fear
-Why burnout can happen when you stay in one dominant state for too long
-How to create the conditions for flow instead of waiting for it to happen
-How your physiology can overpower even the strongest mindset work
-Why reaching for your phone first thing in the morning can immediately affect your state
-Why attaching your identity too tightly to achievement can become dangerous
Deri also shares the deeply personal experiences that shaped his philosophy, including the death of his father, confronting regret, facing life-threatening moments in extreme environments, and learning through fatherhood how easily intensity can follow us from work into the relationships that matter most.
