My dad has always been my coach. And I've spent so much time with him. So he's one of my best friends. And I can talk to him about everything.

I do my best, and that's all I can do.

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 just like being around people, especially nice people, and there are a lot of nice girls on tour.

I'm just taking one match at a time.

One day my dad would say, 'OK, if you want to play tennis I can help you out.' And that's how it started. And I had a goal. I wanted to beat my mom first. And my parents and my brother. And that was the ultimate goal.

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