"Stop performing your worthiness through endless achievement – you're already enough. Fleur gives you permission to reclaim yourself, take up space, and build success that doesn't cost you everything. This book is the wake-up call every overachiever needs before they break."

– Erika Cramer - The Queen of Confidence

"Sometimes it takes tragedy to wake us up. For me, losing my husband to cancer at 54. For Fleur, nearly losing everything proving she was enough. Now she's dedicated her work to helping overachievers stop making the same mistake—and this book is the blueprint. For every leader who's been so busy achieving they've forgotten to actually live, you must read this extraordinary book. Ask yourself whether your definition of success is costing you too much, and follow Fleur's advice to listen to the whispers before they become screams. Because life is too damn short, and later might be too late."

– Kate Christie - Best selling author of The Life List

"I've had a front-row seat to Fleur's astonishing transformation - watching her lead with impact while navigating serious illness, always showing up and delivering excellence, then reshaping her entire career from agency leadership to helping other leaders avoid the same fate. What makes The Overachiever's Reset powerful is how it shows you can pursue ambitious goals with the good kind of power - the type that doesn't require you to betray yourself or sacrifice what matters most. Her profound story combined with this proven blueprint will help so many leaders find their way to sustainable success."

“A beautifully honest and powerful book for anyone stuck in the relentless cycle of doing more and feeling less. Fleur Marks offers a compassionate wake-up call and a roadmap to success that no longer comes at the cost of your health, relationships or sense of self. Essential reading for modern high performers.”

– Sarah Grynberg - Speaker, Author & Creator of A Life Of Greatness Podcast

“This isn’t just another personal development book – it’s a wake-up call for high-achieving women who’ve spent too long chasing external validation, all while slowly losing themselves in the process. Fleur’s journey is raw, real, and utterly relatable because she’s lived the collapse and rebuilt from the inside out. The Overachiever’s Reset is the blueprint we didn’t know we needed – a call to stop performing, start listening, and finally lead from a place of enoughness. I’ve had the privilege of walking beside Fleur as she stepped into her truth, and this book is the permission slip for so many others to do the same."

– Janine Garner - Author, Speaker, Business Mentor

“"I worked with Fleur on the Qantas rebrand whilst she was navigating treatment - and she showed up, gave it everything, and delivered like the professional she is. It blew me away. When she shared her story with my marketing team at the time, it changed how they thought about leadership and success. The Overachiever's Reset is what every leader needs to build sustainable teams and businesses that actually last.”

– Stephanie Tully - CEO Jetstar

“So much leadership development focuses on doing more, pushing harder, proving yourself to others. The Overachievers Reset does the opposite and that’s why it matters. It’s a thoughtful, practical guide to let go of the need for external validation and, instead, lead effortlessly from a place of deep self-knowledge and authentic strength.”

– Sherilyn Shackell - Founder & Global CEO - The Marketing Academy

"I heard Fleur speak over a decade ago and her story stayed with me—then our paths crossed again recently and I watched how she'd transformed through such adversity to create real impact. The Overachiever's Reset is the book I wish every high performer drowning under unrelenting standards could read."

– Suzana Ristevski - CMO Google Australia & NZ

“I've known Fleur since our Ogilvy days, and I consistently saw her perform at an extraordinary level, delivering outstanding results even when the stakes were sky-high. Reconnecting recently, it was truly inspiring to witness how she’s channeled that intensity, transforming it into a powerful engine for sustainable impact. Her new book, 'The Overachiever's Reset,' is precisely what so many leaders need: a practical guide to building truly fulfilling careers without the constant threat of self-sacrifice. This isn't just a book; it's a critical conversation our industry has been waiting for."

– Marie-Claire Barker - Global Chief People Officer WPP

“I've been that overachiever quietly breaking under impossible self imposed standards - and I've watched brilliant founders do the same. Fleur's story is the wake-up call we need. This isn't another hustle-harder playbook. It's raw, real, and gives you the sustainable blueprint to achieve your wildest ambitions without sacrificing yourself. Read this before you break.”
