Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

I'm proud to be a symbol like the army knife or the mountains.

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.

The more I lose, the more they believe they can beat me. But believing is not enough, you still have to beat me.

When they [court announcers] say, 'This is the world No. 2,' it just doesn't sound right to me because either I'm No. 1 or I'm a grand slam champion. I'm not world No. 2. I just don't like the ring of it when I'm introduced on court because I've been up there for so, so long.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

One or two years ago, I didn't know who I was on court and I used to swear a lot. But now I've learned how to cope and can therefore win 10 matches in a row. I want to be remembered as a good player rather than an idiot on court.
