If I'm nervous, it means I had to work hard to get there, whether it's playing in a tournament or speaking at an event. So I try to stop and be proud of getting to live in that moment.

I've been very competitive by nature from a young age, whether it was eating a bowl of pasta faster than somebody else, or always wanting to be the first one in line.

Music is a part of my life all the time - on the plane, before matches, driving out to the court.

It's strange for my friends when they see me on TV and in magazines, because the person that they see doing interviews and pictures on the red carpet is not the person that they know.

I go to yoga classes and work on my core.

I don't have to follow any special diet or count calories. I try to eat healthily and before a match I load up on pasta and salads. But I pretty much do what I want.

I want my handbags and my shoes to be stylish but I want to make sure that they're versatile. I travel and I have to make sure the pieces I put into my bag can go with a dress or with shorts or jeans.
