The ambition that built your career shouldn't be the thing that breaks you
You’ve built an impressive life. You deliver, you perform and you rise to every demand. Yet beneath the achievement is a quiet truth many high performers recognise: the version of success you’ve been living is no longer sustainable. If you feel stretched, tired or unseen inside your own life, you are not alone. Author Fleur Marks was a relentless overachiever until a health crisis forced her to confront the cost of this pace. What followed was a radical reset of how she lived, led and defined her worth.
This book is that reset. It doesn’t ask you to reduce your ambition. It offers a new way to pursue it, without losing yourself in the process. You'll uncover the beliefs that drive overachievement, neutralise unhelpful perfectionism and build a healthier path to impact, influence and fulfilment.
- Name what’s breaking you: Recognise the invisible forces driving you to the edge, and understand why everything that made you successful is now quietly tearing you down.
- Reset your mindset from the inside out: Master the three shifts that change everything: say enough already, drop the masks, and loosen your grip.
- Redefine success so it includes you: Stop chasing more at the cost of yourself, and create your own reimagined ambition.
- Lead with impact: Discover how to show up intentionally, set brave boundaries and create more impact by focusing on what matters.
- Make it stick with your reset blueprint: Implement the practices, rituals and systems that turn sustainable high performance into your new way of life.
You don't have to wait for permission to live and lead differently. A different way becomes possible the moment you choose it. Start your new beginning right now, wherever you are, with The Overachiever’s Reset as your roadmap.
