I can recommend the book. I've read it the day it came out. Of course, it's some kind of compilation of the stuff you could already read on Leo's homepage. But anyway: it can't be wrong if you read about the same thing twice. I love Leos work. Along with Tim Ferris, Randy Gage and George Leonard (wrote the great book "Mastery") he has been one of my most important teachers as an adult.
Tim Ferris is too pretentious for my taste.
