I recently downloaded the book and admit it is a book that is going to create a bit of a paradigm shift in instruction, by creating an approach to golf development inclusive of the mental game. The book truly provides the means for any golfer to hone a mental approach to the game that results in rapid improvement. The golfer is left to create the mind state just like they would create and establish a swing. You can go to iBooks and review portions of the book for yourself, to make your own decision. I certainly do not regret the purchase. You will be intrigued by what you read.
