The Importance of Self-Truth in Exercise

I cried a lot while I was writing this book because exercise is not just about moving our body. If we can believe ourselves and we say we're going to do something, it's a hugely important thing. And also like evolution wise, exercise is weird. Animals play. They do not make themselves go for jogs at six o'clock in the morning when they do not want to. So if you read the book and you feel better about where you are just now, that is the dream.
