This book cuts right through to what all tennis players inherantly know, your success on the court is directly related to what is going on in your mind. You realize that your body knows how to play, and needs no gratification or instructions by your inner critic. The less you interfere, the better your body will perform. When your mind is quiet and trusts your body's abilities is when it is has the freedom to perform.
My game improved dramatically since my first match after I read the book, one technique is to occupy your mind into silence by focusing it on something. The thing I focused on was the spin of the ball as it came to me. When I began to concentrate on that, my mind was silent and focused on the ball. When I do this, the ball seems slower and bigger. All of my strokes improved by doing this. Another thing I got out of this book is to let go of all of your lessons and ideas of how to move your feet, how to hit the ball, how to angle your raquet head. A match is no time to ponder these things it is a time to do them. When in a match, just let your body do what it knows how to do. Don't focus on details, just focus on the goal of making a good tennis shot.
All of this is wonderful, but the best thing this book has to offer, is giving the reader the understanding of how to learn in a natural way without your inner voice giving approval or disaproval. And that is a skill that will apply to all things in your life.
I can't wait to read the Inner Game of Work.
