Garland,
I think that is everybody (including mine's) problem. Its fascinating how the mind works, and how important it is in, life, and in golf. Why do tour players, with the same level of talent, post remarkably different seasonal results? Their mind. Short game might help too hehe. But I do not think you have any chance of having a short game, with a poor mind. A strong mind leads to strong play around the green, and especially on the green.
This is where everyone struggles. Garland, what is your best round ever? Whatever it may be, you, yourself, Garland, shot it. Why would you ever be thinking of topping or slicing a ball, when you have PROVEN, that you are more than capable. Oh, how the thoughts begin to creep in!!
To hit the backspace button on your novel, there are a few things that you can do, to help refocus the mind, to an instinctual and non analytical frame. The Waggle. Watch Jason Dufner loser this week in the play off. He waggles four, or five times, way up to hip high. After his waggles, he pulls the trigger. There is virtually no delay between the waggle and his motion. Tiger takes a couple waggles, one last look, and boom hes off. The waggles, the movement in your feet, and your look ups to the target, will help relax the muscles in your arms, and hands, provide a feel of the club and the tempo, ultimately leading to reduced tensions in the mind and body. This will also keep you away from the static position that is oh so dreaded. The pre shot waggles and movement, are like, you running the floor to an open spot, or more likely, your favorite spot. When the ball is there you are ready and BOOM, swoosh!
When you are over the ball, run to your favorite spot! Something that relaxes your mind, and eases your tensions. The beach? Mountains? Farm land, the woods? Cake? Pumpkin Pie? Doesn't matter what flies your kite, just get flyin! When you are moving over the ball and relaxing, when you are ready to execute the shot, the ball is already there and BOOM!!
I would read the book Golf is not a Game of Perfect by Dr. Bob Rotella. Nothing better out there, IMO. The mental game, is a highly overlooked aspect of the game, and most people would benefit from giving it more attention. No matter what your ability, tour player, weekend player, beginner, Dr. Rotella puts it out there easier for you to understand. His work with other athletes at UVA, provide cross references that apply to the mental game of golf. I would highly, highly recommend this book, if you are serious about improving your golf game.
