Rotella takes you inside the head of many of the tour players he works with which makes you realize the struggles these guys face and they play the game for a living hitting balls most every day. As an example, Nick Price mentions in the book that he would rather not knock the ball close on the first hole because if he misses the putt it sets a bad precedent for the day. He would rather knock it to 25 feet and 2 putt. I couldn't believe that the first time I read it coming from a successful tour player. Rotella teaches you how to get in the proper frame of mind when heading to the course. He talks about preshot routines, course management and how to handle adversity during a round. I went from a solid 8 handicap to a 5 within a couple of weeks after reading it and have since dropped to a 2. Without a doubt, the most influential book I've read about the golf game. I recommend it to all my friends.
