A great tennis career is something that a 15-year-old normally doesn't have. I hope my example helps other teens believe they can accomplish things they never thought possible.

Without my dad, I wouldn't be here.

I love getting consumer reports. I think it's one of my favourite things, studying what people have to say about the product and then trying to make it better.

My next goal is to be number one in the world.

I think when you have surgery on any part of your body, it's never going to be the same.

I owe a lot to my parents.

I don't need many things. I don't need glamour and attention to be happy. I'm very happy being settled and working my butt off and trying to win grand slams.
