I have been a fan of Jamie Smart's work for years, dating back to his NLP days. When I first discovered the 3 Principles two years ago (spurred by the very sexy title "Do Nothing" by Damian Mark Smyth), I started buying every book I could find on the topic and quickly found Jamie's first book "Clarity." I like Jamie's voice and found the book intriguing, but felt it starting to ramble and gave up on it twice before I finally finished it. Still, I liked the book and would have given it a 4 out of 5.
This "Little" book hits all the right buttons for me, flows well and reads quickly (which for me means I will re-read it). I also especially like the 3rd part of the book. I will happily recommend and even give this book to friends and clients.
