Query: this guy is a good mentor

the book is a very easy read and in no way does it show content that is unimportant or unneccessary. the parts on stopping bu_ttheads on their tracks are specially good and enjoyable. learn some stuff about psychology that is actually real and works everyday, its scary if this book were five stars. it would probably be some sort of magic.
