This book was a gift. The entire book is filler. He talks about his audio course, website, promotes himself at every opportunity. He asks you to leave a review on Amazon to help him "spread the word". Some of the (very basic) techniques are valid, but he sites them with links to pop science articles and has no qualifications to present these as his own. I could have done this "research" on my own. I cannot explain how much I dislike this. Total waste of time even to skim through it.
