I loved this book by Bruce Elkins. It was really easy to follow and understand. He gives great examples and stories about real people that I could relate to. He includes diagrams to make his concepts even clearer for those of us who are more visual. I have actually used some of the things he put in the book and found it incredibly useful. I would recommend this book to anyone looking at changing their lives for the better, trying to create what really matters in their lives or going the simplicity route.
