I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

I haven't had a cramp since '99. That was my only time, in Davis Cup, when I was panicky. I was young. I'm very proud of that. Never pulled out. Never had cramps. Never lost very much because of fitness, especially later on in my career where I knew I've put in the hard work. I've done that. I've been very fortunate and clever as well to understand how I need to work, when I need to work. So I'm very happy to have stayed injury free for so long. I hope I can still maintain a few good years on the tour. I really hope so.

I'm playing great tennis. I'm enjoying the tour, having fun with the fans off the court. I'm loving it now.

I don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

The nicer the point, the more -- the better I feel, the more excited I get. But I never play that my opponent looks stupid. I think that is wrong. I have too much respect for every opponent I play.

Every match I go into, I'm the huge favorite. I lose a set and it's, like, crazy.

When I was 12 years old, I was just horrible. My parents were ashamed to watch my matches. I would play on a court at the local club and they would watch from the balcony. They would scream, 'Be quiet' to me and I would scream back, 'Go and have a drink. Leave me alone.' Then we would drive home in a very quiet car. No one speaking to each other.
