”Single most transformational framework for personal growth.” Camilla Hermann
This book changed my life and has ignited transformation in leaders, teams, and organizations around the world. Meet these pages with an open heart and an open mind, and the possibilities for how you live and lead with clarity and courage are truly limitless.
“[A] refreshing wake-up call to anyone who thinks that work is a self-driven, zero-sum game.”
“[A] serious invitation to radical self-inquiry—the kind leaders must undertake if they are to stop unconsciously passing their wounds downstream.”
“The 15 Commitments cracked something open in me that no other business or leadership book ever has.”

A practice, not a quick fix
These commitments are not techniques you master in a weekend. They are ways of being you live into, one moment at a time. The book gives you the practices. Life gives you daily chances to use them.
