I'm Serena Williams on the court, but away I have so many different names. I call myself Butterfly.

I like to wear classic silhouettes and add a punch to it.

Since I don't look like every other girl, it takes a while to be okay with that. To be different. But different is good.

I think I can improve a lot. I think I can get a lot better. I feel like there's much, much more I can do.

Think of all the girls who could become top athletes but quit sports because they're afraid of having too many defined muscles and being made fun of or called unattractive.

I was having an out-of-body experience, it was so hot. I felt I was watching someone play in a blue dress, and it wasn't me.

I can't become satisfied, because if I get satisfied, I'll be like, "Oh, I've won Wimbledon, I've won the U.S. Open. Now can I relax." But now people are really going to be fighting to beat me.
