Counting on your opponent to inform you when he breaks a rule is like expecting him to make fun of his own haircut. Never leave your opponent with the sole responsibility for thinking of all the things that might go wrong with his shot. Taking more than two putts to get down on a lightning-fast, steeply sloped green is no embarrassment unless you had to hit a wedge between the putts. Never subtract so many strokes on any one hole that you wind up with the honor on the next hole. The statute of limitations on forgotten strokes is two holes.
Nonchalant putts count the same as chalant putts.
It's not a gimme if you're still away. Always limp with the same leg for the whole round. Nothing straightens out a nasty slice quicker than a sharp dogleg to the right. The shortest distance between any two points on a golf course is a straight line that passes directly through the center of a very large tree. It's often necessary to hit a second drive to really appreciate the first one.
