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 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.

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.

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

I'm not going to give in to the critics. I'm going to stop on my own terms, not on when someone else thinks I should.

My goal one day is to be in the same sentence as Rod Laver and Ken Rosewall.

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.
