Episode 91: The Overachiever’s Reset: Redefining Success When Life Forces You to Stop with Fleur Marks

Have you ever been forced to stop… and realised the way you were living or working just wasn’t sustainable anymore?

Like something in your life hit pause - and you were left questioning everything you thought success looked like?

In this episode of It’s a Mindset, I’m joined by Fleur Marks - globally recognised leadership trainer, performance mindset coach and author of The Overachiever’s Reset.

Fleur built a highly successful career over two decades in senior leadership, driven by ambition, high standards and relentless performance. But that same pace ultimately led to a life-threatening health crisis - what she describes as the “waiting room of death” - forcing her to confront the reality that the way she was succeeding was unsustainable.

What followed wasn’t a step back from ambition… but a complete reset. In this deeply honest and powerful conversation, Fleur shares how she rebuilt her mindset, redefined success, and now helps high performers break free from the overachiever’s cycle - where self-worth becomes tied to achievement and external validation.

I was deeply moved by Fleur’s strength of character and her ability to stay positive through such significant health challenges. This conversation is a reminder that true success isn’t about doing more - it’s about understanding what matters, and learning to lead and live in a way that supports both performance and wellbeing.

Key Episode Takeaways:

• How Fleur navigated major health challenges and used them as a catalyst for change
• Why so many high performers are trapped in the “overachiever’s cycle”
• The power of radical self-acceptance in breaking free from relentless striving
• How believing you are enough could change everything - for you and those around you
• The importance of focusing on what’s in your control and consciously choosing your response
