I'm not an overly emotional or hyperbolic person...but (you knew that was coming) this book is life changing. It validated ideas I already had, provided me with more useful information than any book I've read in the last 10 years, entertained me and ultimately inspired me in all sorts of ways to be a better husband, a better son, to sleep more, to challenge myself intellectually in ways that a re real and lasting. You'll want to read it again and again. I'll loan you one of my many copies.
