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.

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

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.

I think I'm a really tough player.

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

I'd like to do a lot of things - whether in design or architecture or business.
