The worse you're performing, the more you must work mentally and emotionally. The greatest and toughest art in golf is "playing badly well." All the true greats have been masters at it.

When you lip out several putts in a row, you should never think that means that you're putting well. When you're putting well, the only question is what part of the hole it's going to fall in, not if it's going in.

You don't think anything about age when you're playing [golf]. I mean, why would you ever think about that.

1960, I was 20 years old, and I was leading the U.S. Open. Now, I wasn't leading by several strokes, but I was leading the U.S. Open and playing with Ben Hogan, had a very good chance to win, nine holes to go, I was leading. I was still leading with six holes to play.

You're not going to tell me that you're going to find a person who's not a very good athlete and he or she is going to be a great player. But anyone can play the game. That's the nice thing about the game. You don't really have to be a world-class athlete to play the sport [golf] and have fun because of handicap systems.

I came back and in '63, I was at the British Open, trying to win my first British Open. And I had what I thought was a two-shot lead with two holes to play at Lytham. I remember it like it was yesterday. Anybody with a proper brain would have played the ball short of the hole. I didn't have a proper brain at the time. But you have to make that mistake to learn it.

Golf was my vehicle to competition and I can't play if I can't compete.
