I was lucky enough to get one of the first run copies of this book. The Secret is and will be what he's most known for, but I believe this is a condensed version of that piece of marketing. Along the same lines as positive thinking changing the way you believe, this book is about a clinical look at why and how your body and mind reacts when you make the choice to be happy and make the choice to be positive. In a world of equal and opposite reactions, being positive pays dividends to everyone involved. It helps in job interviews, in love and relationships, and miracles DO happen when you can fully express the joy and happiness from within. Which starts with you re-evaluating where the darkness comes from and extinguishing it.
