On the PGA Tour, guys finish in the top 10, make a ton of money and think they're great players. In my era, you had to win. We didn't settle for anything else.
I just never subscribed to the theory that at age 55, you fall off the face of the earth on the Tour. I always felt that was too young of an age for that.
Do I want to tackle a 230-pound guy who's running like a deer? Heavens no, no one in their right mind would. But there is something that drives me and compels me to stick my head in there and give it my best shot.
I've felt that if you dwell too much on your errors, you're dealing in the negativity of things. I don't like that. I'd rather work on the positive reinforcement, the things I did well.
Feeling tired should almost never be an excuse, because your body has huge reserves of energy. But if you eat badly, stay out late, drink too much, and so on, you'll pay a price on the course.
