Query: A MUST Read!

I first bought this book for my kindle. After reading about 20% of this book, I immediately went online and bought a copy for my mom. After reading about 40% of the book, I again went online and bought myself a paperback copy so that I could carry it with me wherever I go. I know that this will be a book I read over and over again. A great quote from this book, which I believe summarizes what this book does, is: "knowledge isn't power until it is applied; and the purpose of this book is not to tell you something new. The purpose of this book is to remind you of what you already know and to kick you in the shins and inspire you to do something about applying it."
