Query: Here's your one decision - PASS ON THIS BOOK!

I bought this book based on the stellar reviews it had gotten. After reading it, wow, what a mistake. This is the worst book I have read on the subject - seriously. There's a lot of fluff and not much substance. Wayne Dyer and Carolyn Myss offer much more meaningful material - check them out instead.
