I am someone who likes to stay positive.

The thing about tennis is if you stay off for two weeks, or just for three days, you can lose your rhythm quickly. So it's just a question of constant diligence and vigilance.

A win's a win, unless it is not a win, and then it's not a win.

Winning once is never anyone's dream. We all want to keep winning no matter what it is, or if we retire, we all still are striving toward something, probably most of us are.

I always like to win. But I'm the big sister. I want to make sure she has everything, even if I don't have anything. It's hard. I love her too much. That's what counts.

In the sports arena I would say there is nothing like training and preparation. You have to train your mind as much as your body.

Everything is tennis for me, it's my career and it's entertainment, but it's also a business.
