In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.

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.

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.

There is nothing like playing at Wimbledon; you can feel the footprints of the legends of the game-men and women-that have graced those courts.

I tend to be slim and you know, I actually can lose weight quicker than I can gain it.

Sport teaches you so much, and you can translate that to other parts of life. But it's definitely a lot of dedication, not just for, you know, myself or the children, but the parents, the family finances, the money that you could be putting toward retirement you're using to buy tennis shoes and restring rackets and tennis lessons. So if you don't make it, then you may never retire. It's definitely a lot of risk.

I think everyone deals with things in their own way. Everybody's different. My family are all different. None of us are the same. We all deal with different things in different ways. I think it's about knowing yourself, what pushes your buttons, and figuring out how to work with yourself.
