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.

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

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.

I like Twitter a lot. It is a great way to get the fans knowing another side of you.

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

I like to be with my friends and my family, listen to music and read books. Things like that relax me.

There are so many tough opponents out there and tough competitors so I've never liked to look ahead.
