I don't want to give the impression that my sessions at the driving range are haphazard; they're not. Often I take just 1 or 2
clubs and work on those exclusively. I usually have a specific thing I want to work on--backswing, grip, whatever--maybe something from my lessons. Sometimes I bring a notebook and log every stroke, what I did and what happened. I've videotaped my swing 5 times now, and I'm getting pretty good at spotting the problems. I've learned a lot about the golf swing! But even seeing my head bobbing around doesn't help me to keep it still...
I have some of the books you mentioned, and a few that you didn't, such as Newell's Golf Instruction Book, and Ernie Els's How to Build a Classic Golf Swing.
It's funny you mention the short game. My chipping and lobbing are probably better than my friends', and my putting is no worse. The problem is, it takes me 5-6 strokes to get to where I can chip!
Often I'll go to the driving range and practice and, after 10 or so balls, things may start to click and I start striking the ball well. But it's as if I have only short-term muscle memory; the next time I go, I'm back at square one.
Well, I'll just keep on keeping on. I think I'm as addicted to working on my swing as I am to the game itself. Thanks for the comments.
