I just go out there and fight for every point, and then we see how far I can go.

I think I'm a really tough player.

My parents paid me small amounts for cleaning my room or cleaning the dishes and stuff, but I never really had a real job before I started on my professional tennis career.

I never give up. Doesn't matter what the score is.

I don't know, I always get the question 'how do you feel after the game today?' and, of course, if you're winning you feel great and if you lose you don't feel good. I think that's a pretty obvious question.

You feel better about yourself when you do something with yourself. You also feel more confident.

It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.
