Confidence evaporates in the presence of water. A putt is not a gimmie if your are still away. The rake is always in the other bunker. The wind will be in your face on 16 of the 18 holes. You always have the honor on a tricky par-3.
Nothing straightens out a nasty slice quicker than a sharp dogleg to the right.
The ball always lands where the pin was yesterday. Your straightest iron shot of the day will be exactly one club short. If you seem to be hitting your shots straight on the driving range, it's probably because you are not aiming at anything. Since bad shots come in groups of three, a fourth bad shot is actually the beginning of the next group of three. The only way to ensure a par is to leave a four-foot birdie putt two inches short of the hole.
