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.

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

The difference of great players is at a certain point in a match they raise their level of play and maintain it. Lesser players play great for a set, but then less.

Retirement is a work in progress. I try to figure out my day, and what I know about myself is that I need structure.

I admire the way golfers handle themselves. But tennis players are a lot younger, as a rule. There aren't many teenagers on the golf tour.

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

For so long people have just taken what I do for granted. It is not easy to do year-in, year-out, to win Grand Slams and be No. 1.
