Why Quitting Isn’t Failure | Gareth Holebrook on Ishi

What if knowing when to quit is just as important as knowing how to persevere?

In this episode of the Forking Good Podcast, Simon Gault and Kate Fenwick sit down with leadership, health and triathlon coach Gareth Holebrook, author of Ishi: The Discipline of Determined Intent.

Gareth explores the philosophy behind Ishi and what decades of business, coaching and extreme endurance racing have taught him about determination, leadership, failure and burnout.

Having completed more than 30 iron-distance races, Gareth knows plenty about persistence. But some of his biggest lessons came from the times he persisted for too long — including spending five years pursuing a business that wasn't commercially viable. His message? Giving up isn't necessarily failure. Sometimes, knowing when to abort is a skill.

The conversation explores Gareth's Ishi Spiral, his Adjust–Hold–Abort framework, why writing down your intentions can change your behaviour, the power of deliberate practice, and how asking what your future self would think can lead to better decisions.

They also discuss Japanese philosophy, Kaizen, leadership, Ironman racing, burnout, business failure and why high performers can sometimes become victims of their own determination.

If you're ambitious, constantly juggling competing priorities, struggling to finish what you start — or doing so much that you're heading toward burnout — this conversation is for you.
