“This book is a great resource for understanding and building better habits. The 90-day plan is practical and easy to follow, and the explanations of how habits are formed are clear and helpful. I especially liked Chapter 7 on healthy eating—it’s full of great tips for staying on track even with a busy schedule. Chapter 8 on rest and recovery was also excellent, particularly the advice on optimizing sleep and preferred sleeping temperatures. I definitely recommend this book for anyone looking to improve their habits.”
