forthcoming memoir
Erin Renzas’s debut memoir is a takedown of the fairytale we’ve been sold about success, identity, and self-worth—and an unflinching exploration of what it takes to rebuild from the inside out.
Set inside a boxing gym, the book opens in the aftermath of success: the title, the million-dollar career, the polished, high-achieving life that looked perfect on paper—but felt quietly suffocating. It traces her years-long transformation from high-functioning executive to someone forced to confront the cost of perfection.
Through a period of collapse marked by dissociation and the gradual erasure of self, Erin examines how ambition became a mask and achievement a center that could no longer hold. The turning point came in a boxing gym in Amsterdam, where she began learning how to fight differently—not by abandoning what she had built, but by reclaiming it on her own terms.
Told through the strategy of the ring and the intelligence of the body, the memoir invites readers into an embodied inquiry into ambition, identity, and self-worth. Boxing is not metaphor here, but practice—revealing how we move under pressure, absorb impact, and respond with clarity and intention.
The story explores the quiet unraveling beneath high-functioning surfaces—and what it takes to build a life that’s real, embodied, and self-authored. It challenges the cultural scripts around burnout, dysmorphia, hustle culture, and the performance of empowerment—and offers something more grounded in their place.
Written with precision, physicality, and emotional clarity, this is not a story of escape—it’s a story of return. A return to self, to truth, and to a definition of success built from the inside out.
