[Golf]is deceptively simple, endlessly complicated. A child can play it well, and a grown man can never master it. Any single round of it is full of unexpected triumphs and perfect shots that end in disaster. It is almost a science, yet it is a puzzle without an answer. It is gratifying and tantalizing, precise and unpredictable. It requires complete concentration and total relaxation. It satisfies the soul and frustrates the intellect. It is at the same time, rewarding and maddening. And it is without doubt the greatest game mankind has ever invented.

Winning is a drive, it's a thing that you feel like when I go to bed at night I go to sleep.

I can't afford the luxury of music while I'm flying an airplane. I have to pay attention to what I'm doing.

Phil [Mickelson] has done a great job. He's a great player and he's conducted himself very well through the years. He's been a good ambassador for the game. He hasn't won in a while, but he still has time, and it wouldn't surprise me if he won again.

I think the people I have met have meant a great deal to me, more than any shot I ever hit. I will always remember some golf shots, but others I would like to forget.

I stopped playing in the Masters in 2004, I stopped playing in the Par-3 [Contest], and now it's time to end this part of my Masters career. I would love to go on doing it forever, but I don't have the physical capability to hit the shot the way I would want to hit it. So I'll have to be content to watch.

Many people don't know that I experienced a blood clot caused by deep vein thrombosis, or DVT, which is when a blood clot forms in a deep vein in the body, often the leg or thigh. I'm fortunate that my DVT was diagnosed and treated before it led to something even more serious and that's why I encourage people to talk to their doctor if they think something is wrong. I've teamed up with Janssen Pharmaceuticals to raise awareness about blood clot prevention and treatment.
