Book excerpt: You should read this book for a very fundamental reason; one of the profound realizations golfers ultimately make in the effort to improve is that Bobby Jones was right about managing the course between your ears. The problem is that it is difficult to do. For the first time, this book gives you a real understanding of how the brain works to help you. We have distilled very complex concepts into simple language, and have given you proven techniques to utilize the power of your mind. Play well and enjoy. Jim Yockey Having spent a career studying and writing about language, psychology, brain functioning, and human behavior I can without reservation assure you that using the scientifically sound precepts in "Playing With Your Mind" will help you develop a better golf game. Moreover, you may find the techniques useful in many areas of your life. What I know about golf is that it requires creative thinking and persistence to play well. Read this book with that same search for insight and you will be rewarded. Harry A. Whitaker
