I'm a big supporter of this product for women. And [my relationship with the brand Berlei] was so organic. I would go to the store and buy 40 or 50 bras every year because I could only get them in Australia at the time. And then eventually they heard that I would come and take all the stock.

I wanted to get really fit. I wanted to lose some weight. So I've been doing Pilates and yoga, trying to lean out my body so I won't be bulky.

It's so great to have that opportunity with so many young American players coming up now. It's just so exciting. We have to root for the home country.

Since I don't look like every other girl, it takes a while to be okay with that. To be different. But different is good.

I really hope that I can be helpful in that journey because I do believe that women deserve the same pay. We work just as hard as men do. I've been working, playing tennis, since I was three years old. And to be paid less just because of my sex - it doesn't seem fair.

I meet people who say, "Girl, I watch every match, and I pray for you." I feel that energy and those prayers. Sometimes when I'm down on the court, in the back of my mind, I'm thinking, "They want me to win. Is there anything else I can give?" It encourages me to do better, to fight harder.

I love metaphors. I've never been on this train. ... If I'm standing on the middle of a track, I'm definitely going to get derailed. I have to make sure that I'm on the train and not in front of it.
