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.

The big push for me is the Olympics this year. If I'm healthy, I'm not worried about my ranking. I think I can hit the ball. It's just about my body cooperating. It's about being able to play matches in a row. Right now, I'm not sure how much I can do with that, but we'll see.

I can walk around fine, but I don't have a desk job.

At the end of the day, you just have to focus on winning. No one can take a win away from you. That's what I focused on. Life is not fair, so I don't go out there expecting it to be. I don't think any of us should go out expecting life to be fair. I think that's expecting too much, and I remind myself of that sometimes. You can get on with your life after that.

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.

So what if you fail? At least you'll know what not to do when you try again.

I guess tennis is my main art, but fashion is definitely very close.
