So you think about every shot, every hole, try not to worry about your opponents, and do the best you can. When you play golf some people do things differently and may unnerve you. But that's the way golf is played, and you just learn to cope with it. The more golf you play you realize that you can play well regardless of what else is going on around you. The good thing about tournament golf is that it teaches you how to compete.
Golf is a game of etiquette.
The rules are strict and they're fair. It's very good that in golf you have to call penalties on yourself. The ultimate decision is always on you the player. As a rules official, I come in and ask the player, and I base my decision on what they tell me.
