Playing better/worse than you think

[tongzilla]

Why do most of us have a bad day when we think we're going to play very well, and vice versa?

And sometimes, if you prepare a lot before a round, you end up playing worse, and if you don't prepare at all, you play very well.

"Davis Love III was told his tee time was 11:14 a.m., but it sounded to him like 11:40 a.m. He was in the fitness trailer when he saw the tee times, rushed out the door and went to the first tee without warming up. "I hit driver and 1-iron to 20 feet and made eagle," Love said with a laugh. He shot 67 and was at 12-under 204."
