If I didn't play tennis I don't know where I'd be.

We've been training and playing full-time since we were 18 and 19. So after tennis, we'll be excited to see what it's like to have more free time.

I wear a lot of tight dresses, so I'm like, 'I need to do my sit-ups!'

I truly believe that whoever feels the most confident is usually the one to win.

'Oh and Oh' is a tennis term... It's a nice way of saying you took your opponent to pieces.

I most certainly believe that when you're an athlete, that really translates to all sports. You just understand it, your body understands it, and your mind understands it. And you just - it just clicks. I've found that happening when I play other sports. I've seen it, like when I've hit the ball with other professional athletes, and you can see they're just learning so quickly. It's just something that's in their blood. So I think it was in my parents' blood and they understood.

Definitely sport matures you, if you let it. It definitely makes you grow up because you have to work so hard that if you can't, then you probably aren't going to have the mental capacity to handle it all. That probably played a role in growing up a little faster than maybe other people.
