This book was refereed to me by a friend who has some experience with youth athletic coaching. Rather than focusing on the skills of the game, he has realized that as an amateur who doesn't always know what he is doing, it is better off to focus on the phycological aspect. The research and experiments in this book were deep, but extremely interesting and truly inspirational. After reading this book, my entire mindset on sports had changed. This check of perspective based on science made for an interesting book and greatly helped my golf game, which is very mental based. Anyone serious with athletics should read this book.
