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.

Well, when I walk behind short people I feel like I'm going to fall over because I start taking these little steps, and I can't take little steps.

I don't come to tournaments to make friends, to go to parties, to hold conversations. I come to be the best, and I'm not mean and cruel and dirty.

It is very important not to think about losing.

It's a great feeling to have accomplished what I have, but I want to do more.

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.

Grand Slam losses are hard. I treat myself after losses though, I usually go to McDonald's and I have a hamburger and you know, something. Because you know, you just need to be nice to yourself sometimes after the loss.
