About This Book This book is not a promise of calm, happiness, or optimization. It is a guide to understanding why stress persists , why recovery feels elusive , and why so many well-intentioned self-help strategies fail —not because you are doing them wrong, but because the body is still prioritizing survival. The ideas here are grounded in neuroscience, endocrinology, metabolism, and stress physiology. They are presented in plain language so you can work with your biology instead of against it . This book is not about pushing through stress. It is about teaching the body when it no longer has to .
