The game is meant to be fun.

I've never set up any golf course that would favor anybody. I try to make it exactly the opposite, which is what we did at Valhalla when we modernized it to accommodate the lengths players are hitting it today.

When I fly in a helicopter, I insist there be two sets of controls, one for me in case something happens to the pilot. I'm no expert, but I know enough to at least get the thing on the ground. Nothing scares me like the thought of not being in control.

Tom Watson, Tom Watson blew, what, two PGA Championships and a U.S. Open. Did it destroy his life? No, it didn't destroy his life. He learned from it. He went on to win a lot of major championships and obviously became one of the world's great players.

Sometimes the biggest problem is in your head. You've got to believe you can play a shot instead of wondering where your next bad shot is coming from.

We're not perfect every time. We make mistakes just like everybody else. But, we stay on top of it, and we stay with it, and we make sure we get it right.

You're always struggling because you're not playing on a 53-and-a-third by a 120-yard field. You're not playing on a baseball diamond. With golf, every field is different and every atmosphere is different. The grass is different. The weather is different. You're outside. You're not in a stadium. There are so many different variables, so you never master golf. So, I think good athletes like a challenge.
