The title seems odd, but before you start your pre-shot routine all your actions affect your shot. I believe that all my actions on the golf course have a direct impact on my game. There is a laundry list of things that will help, but the last thing I want to do is fill your head with white noise. However, there are a few actions I consistently perform to ensure that I am in proper frame of mind to make any shot.
I am sure you have things you do automatically without thinking, yet focused intent is very important on the golf course. I think random acts can detract from your game; they can take your focus from the moment into areas that are not related to what you are doing. It does seem strange, but knowing what you are doing 15 seconds before your pre-shot routine could make the difference between success and that other thing!
The first positive action I perform is to visualize my shot. This is different from what happens during my pre-shot routine, it is more holistic. I weigh the benefits and potential hazards of a shot, but as I walk towards my ball, I notice the lay of the land, the wind, the trees, potential hazards, real hazards, and my stance. Then I think about making the perfect golf shot; I am not be successful, but I am setting the foundation for success.
Next is the placement of my clubs. In the fairway, my clubs are to the right of the ball, two paces behind and two paces to the right. The location of my clubs is important because they are out of my sight line and generally do not cast any shadows that will affect my concentration. This might seem like a superstition, but when I do not place my clubs in this position and they are closer than described; I can feel the clubs, they are in my space and it bothers me.
Talking too much to my playing partners. If I start chatting too much, it throws my game off. I am focusing too much on what they say, than on my game. This usually happens during friendly matches, but not during competition. Unfortunately, golf is a contact sport, but during a competition I am friendly, but more focused on game. I find talking excessively is a challenge to lower golf scores.
There are many more things I like to do before my pre-shot routine. Many are situation dependent and likely unique to my game. I think you get the point that all actions on the golf course have an impact on your game. You just have to figure out what they are and use them to your advantage.
I am a grateful golfer! See you on the links!
