There is no doubt about how hard it is to stay on top in any sport, but to do it in an individual sport for the majority of your career, it is not easy.

In tennis, you can make a couple of mistakes and still win. Not in golf. I played three rounds in that Tahoe event, and I was drained. Mentally, not physically.

I am here for the goal, and the goal is to try to do it again.

I did it my way, and I have no regrets when I look back on my career that it was just a big focus for me.

Winning is about taking your opponent's heart out and squeezing it until all the blood has come out, even the very last drop. There are no prizes for a funny loser.

By putting pressure on myself to develop a great game, I had less pressure to win. These days, I tell kids that the way I grew up, it wasn't about winning. It was about playing well, about playing the "right" way. That approach helped me enjoy the game and develop mine to its maximum potential.

I still feel like my game is very dangerous. I always will have my serve.
