It takes clearheadedness and steady hands to play golf. I constantly make minor adjustments with my insulin to avoid problems. And because my blood sugar tends to get low when I play, I always have food with me on the course. When I was growing up, it was peanut butter sandwiches. Now I'll take a turkey sandwich or something to nibble on.
Golf requires a lot of discipline and self motivation.
It's very demanding physically, but even more so mentally, and I think I play a good mental game. Q. Tiger says the same thing. It's hard to explain, but it has to do with attitude, focus, concentration, and, especially, confidence. You have to believe in yourself in order to play good golf. If you hit a bad shot, you've got to be able to bounce back from it.
