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 have a very close relationship with my parents.

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

Golf can be tougher than tennis when things go wrong, because you can't explain things by saying that your opponent played better than you. It's a cruel sport in that way.

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

As long as I win I'm doing something right.

I have proven people wrong so many times. I was told when I was younger there is no chance I will make the top 100, top 50, top 30. Every time I have proven them wrong. It's kind of nice.
