Psycho-Cybernetics, Updated and Expanded

This book is, in so many ways and for many people, a life changing one.
I've been fascinated by the methods provided by the author to literally change our life, and it's just astounding that a deep understanding of out own mind processes was already available in the 60' right before any other new discoveries.
It's a classic, and it must be read and applied.
Profoundly amazed.
