Some people say I have attitude - maybe I do...but I think you have to.

I remember watching the Olympics at home as a kid. It was one my Dad's dreams to win an Olympic medal.

Most of us have grown up, you know, I think there are very few people who have grown up in a home that was, like, super normal. You know, we all have dispositions because maybe you didn't have a mom or you didn't have a dad, maybe your mom died early or maybe mom and dad argued or they got a divorce or who knows? You have issues that maybe you've started younger or maybe you have your own issues because you have them.

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

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.

When youre on top, youre on top.

My motto has always been that you can't say, 'Oh, it won't happen to me.' You have to say, 'That can happen to me.' So always be aware that things can happen.
