About this episode

What if exhaustion at the end of the day has nothing to do with how hard you worked — and everything to do with the state you were in while doing it? In this episode, Dr. James Bryant sits down with Deri Llewellyn-Davies, a former chemical engineer who spent decades studying peak performance in both extreme sport and the boardroom, to explore the science of flow state and why most leaders are unknowingly blocking their own ability to access it. You will walk away with a clear understanding of what flow state actually is, how to build the conditions that make it possible, and why the state you are in does not just affect your performance — it affects everyone around you.

Key Takeaways

Flow state is not a hack or a shortcut. It requires purpose, a commitment to mastery, and intrinsic motivation. Remove any one of those three and flow will not come.

Technology has not just distracted us — it has hijacked our neurochemistry. The always-on phone keeps most leaders stuck in a high cortisol, reactive state that blocks creativity, focus, and genuine connection.

High performance requires recovery. Athletes never skip recovery after an Ironman. Leaders routinely skip it after a demanding workday. The biological need is the same.

There are six ultra states, not just flow. Flow, focus, peak, recovery, reboot, and ultra connect each serve a different purpose and require different conditions to access deliberately.

The leader’s state sets the temperature for everyone in the room. When you walk in on cortisol, your team feels it immediately. Presence is not just personal — it is a leadership responsibility.

Burnout is not about working too hard. It is about values misalignment, feeling unrewarded, and losing connection to purpose — a distinction that changes how you diagnose and address it.

Identity built on a single thing is fragile. Deri’s second burnout came when the financial crisis stripped away the wealth his entire identity was attached to. Purpose-anchored identity survives loss.

Presence is a decision, not a default. Without an intentional transition between work and home, most people are never fully in either place — and the people around them feel that absence.

Deri Llewellyn-Davies is a former chemical engineer who rose to European board level within a decade before transitioning into management consulting and board advisory work. Over the past 25 years he has advised hundreds of scale-up businesses and has sat on more than 330 boards. His work in ultra endurance sport — including climbing the world’s highest mountains and completing Ironman triathlons — led him to develop the Ultra States framework, which helps leaders deliberately design the performance states they operate in. His book Ultra States is available as a free download at ultra-states.com. He is most active on LinkedIn under Deri Llewellyn-Davies.

Dr. James Bryant is an executive coach, leadership strategist, and host of the Engineer Your Success podcast. His mission is to help professionals win at work and at home by developing the leadership skills and presence that technical training alone does not provide.
