Temper is the one thing you can't get rid of by losing it.
I couldn't care less who I'm paired with. There's nobody I've ever played better or worse with, thank goodness. You don't want any factor to be outside your control. What if Arnie's Army had bothered me? What id I'd said, "Oh geez, I'm paired with Palmer," I'd never had beaten him.
A kid grows up a lot faster on the golf course. Golf teaches you how to behave.
I've had a lot of majors where I didn't play well until the last round. Keep yourself in contention; that's the name of the game. I usually ended up shooting a good round and all of a sudden, somehow, I won.
