I may be a step slower than I was before reaching 30, but I'm doing all the right things. I guess there are some guys who would take it easy in the latter part of their careers, but I'm stepping it up.

With this ranking system, the more you play, the better off you are.

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.

Throughout my career, my mind rarely wandered, and I was never sidetracked by distractions, no matter what I was going through off the court.

I want to end my career on my terms, not on what people think I should do.

After I went through two years of not winning an event, what kept me going was winning one more major. Once I won that last U.S. Open, I spent the next six months trying to figure out what was next. Slowly my passion for the sport just vanished. I had nothing left to prove.

I hate to lose, and I do whatever I can to win, and if it is ugly, it is ugly.
