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.

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

Interior design is a business of trust.

When you step out on the court, I don't think anybody thinks about age. Because if you're out on this tour it means you deserve to be here. You've got the skill. It must mean you know how to play.

I think that Billie (Jean King) and Zina (Garrison), they have a whole lot of experience. Even if I don't quite agree with something or have a different way of doing it this week, whatever they said, I did it right away and I found out that it was correct. I think that's helped a lot...I'm having fun. I had a lot of fun out there. Sometimes I was ready to smile -- but I knew I'd lose focus -- because I was doing things that I'd done in practice and we talked about. I was ready to laugh and give someone a high-five, but it wasn't time for that.

It's amazing when tragedy strikes, how strong you find that you are, and I'd seen other people go through horrible things. And I just thought, "Wow, I would be a complete mess," and then suddenly when it happens, you realize you had more strength than you knew and it helps you to get through.

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.
