This book is called The Everest Principle because Mount Everest is the highest, and arguably the most challenging, mountain a person can climb. Stephen Brewer and Peggy Holt Wagner weave the metaphor of climbing Everest throughout the book as a means to guide you through the trail markers for peak performance. Everyone has, at some point in life, an Everest to ascend. The Everest Principle becomes your 'outfitter' to assess, prepare, train, guide and equip you for the expedition to the top of your personal Everest. This principle requires the use of an integrative approach that addresses your medical, nutritional, physical and behavioural health. Peak performance doesn't limit itself to the elite athlete or performer. It is for anyone who wants to improve his or her individual life. The trek may include real-life challenges such as achieving a better relationship with another, getting a promotion, participating in a 5km fun run, or losing weight. The purpose of this book is to instill you with the belief that you can overcome barriers, attain high-level goals and enhance your life in every way!
