Ben Hogan said it takes 21 days to make something a habit, but you must have that motion correct in your practice and you have to do it repeatedly. That's what he is talking about. We have an area where the student makes notes as he practices so he can provide me feedback and any questions he might have concerning his game or the rules of golf. It really gives the student a way of remembering what he wants to ask when he comes for his lesson. Or we can't remember exactly what the problem seemed to be.
Golfers also are like that.
They can get on the range and even though they hit it terrible yesterday, they can't quite reproduce the terrible shots in front of the instructor. By writing down the problems or struggles they are having or going through, I can answer those questions more directly. The book has a journal area which is important not only from a scores standpoint and history of the details of your game, but also from the standpoint of feelings or swing thoughts that work, or certain practice techniques that you really like and have great success with. We may use 10 different ways to establish the same basic fundamental in your golf swing in approaching it from all different manners and directions, but you may relate real well to one of those 10. Journal that and keep it handy so six months from now you can refer back to it.
