I had a system, and the system worked.

Golf never ceases to be a challenge, even when it really is just you and the ball out there and nobody else.

I have won the Australian, I won the British, all PGA championships, but I haven't won the PGA championship.

I started [flying] by being scared. When I was an amateur I played a couple tournaments and I had to fly, and got into weather and stuff, and it scared me, and I decided that would not work, I had to learn to fly, I had to find out about airplanes and aeronautical engineering and what it was all about.

I think the guys are more conscious of the fact that being in good physical condition under the conditions that they play will make them better players.

I wanted to emulate my father. I wanted to be as tough as he was. I wanted to do the things that he did. I watched him.

I have a tip that can take 5 strokes off anyone's golf game. It's called an eraser.
