This book has been a great eye opener for me. I always had felt that because of my infrequency of play and being way out of shape and carrying extra pounds, I was destined to remain a "duffer" for the foreseeable future. While reading Mr Hill's book I began to visualize how I could improve my game. This came in part due to a lot of the insightful quotes and stories that are referenced, along with the personal experiences of the author. Then, using some of the cross training exercises I found a new mobility in my swing.
My main goal when playing with friends or clients used to be to just not embarass myself. Now I start each round determined to break 100. And it does happen.
