What I've realised is that you can run miles, jump on a bike, lift weights, and all that other garbage, but the bottom line is that you get in tennis shape by playing tennis. You build the right muscles, and I don't believe people can do it as successfully any other way.

My best tennis at my peak was when I played a lot of matches.

I had a harsh lesson in 1996, when I lost four times to Andres Gomez on clay.

I used to get two racquets a year. As you can imagine, they didn't last me too long.

The mistake, if I made one, in the late 1980s, was thinking I needed to change my game.

Of course for your main rivals, you're going to get extra motivated for it, particularly if you haven't played him for a long time.

I can't speak for other people, but I still hate losing. When I did lose, I found it easier to yell than to cry. Guys aren't supposed to cry, are they?

I'm going to vote for Obama. I'm going for the change.

The best thing I ever did was when I was offered a million dollars to go play in South Africa and didn't take it. I was 21 years old, and part of it was like, 'Well, if they're offering me this obscene amount of money just to play one match, there must be something really wrong.'

I thought doubles was a good way for me to practice and get some reps in - I didn't like to train in the gym as much as players these days.
