Although I just started playing last week, I think there could be something to this. I [think] have a pretty natural feel for most sports and the first two times I hit a local 9-hole course with mostly par 3s I was able to get on the green or 2 shot it to the green (putting would kill me). After watching some videos by David Leadbetter and Hank Haney I have begun over thinking just about everything I do and now I'm lucky if I land on the green within 3 or 4 shots on the same course!
Now I am thinking, "Am I gripping the club correctly?" "Am I shifting my weight right?" "Is my club face facing the imaginary target line?" and much much more. Hopefully with a lot of practice though, everything could become repetitive to me and simply rely on muscle memory to be able to get back to 2 shotting it to the green. Then I can start working on my putt game (terrible)!
