Query: It's Motivating.

I admit it. This book does not contain any new or incredible advice. It's all pretty much just common sense stuff. The benefit of the book is that it is very motivating. All of the knowledge in the world will not do you any good unless you actually apply it. The author does a good job of relating his personal stories. You leave the book feeling like you CAN do it.
