I've said many times before that Pebble Beach is a wonderful thinking-man's golf course. That is why it is such a great U.S. Open venue.

Confidence is believing in your own ability, knowing what you have to do to win. My confidence was developed through preparation.

He's going to be around a long, long time, if his body holds up. That's always a concern with a lot of players because of how much they play. A lot of guys can't handle it. But it looks like Tiger Woods can.

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.

A big part of managing a golf course is managing your swing on the course.

The one strongest, most important part of my game is that I want to be the best. I won't accept anything less that that. My ability to concentrate and work toward hat goal has been my greatest asset.

I think we have more good players today [2016] than we've ever had in the game of golf. And I think that's saying a lot because we had a lot of good players when I played. I think you had a bit of a lag in there for a while, that Tiger was just so much better than everybody else that he really didn't put anybody in with him.
