As long as we're fit, we just have so much to give on the court.

Since I started playing at the Olympics in 2000, I have always wanted to do a dress based on Wonder Woman. It should be interesting to wear. And hopefully, it will get me a gold medal.

Serena and I have done some great career planning, and we're playing really at the peak of our tennis right now. I think tennis has been a sport where people play this insane schedule from 14 years old, so of course at 26, it's over. We've really paced ourselves.

Sometimes, you know, once you pay your taxes and once you pay your expenses, once you've lived this life, things add up quickly. And it's easy to become a statistic. And that's something I've always tried to avoid, and I've always said, hey - not that it won't be me, that, hey, it could be me.

Tennis is mostly mental. You win or lose the match before you even go out there.

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

I'm not a trend person. I don't want to look to my right and see somebody in the same thing.
