I always say if I play my best it's difficult to beat me

The mark of great sportsmen is not how good they are at their best, but how good they are their worst.

Labels are for filing. Labels are for clothing. Labels are not for people.

Whoever said, 'It's not whether you win or lose that counts,' probably lost.

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

Luck has nothing to do with it.

Legendary? I don't know. I'm just Serena.

You can't underestimate anyone.

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.

Someone like Billie Jean King is completely my idol.

I've had to learn to fight all my life - got to learn to keep smiling. If you smile things will work out.

I don't go thinking I'm going to lose. I never go into a tournament thinking that. I'll do the best that I can.

I went on the courts with just a ball and a racket and a hope...and that's all I had.

I just hate to lose. When I am on the court, it is like my life depends on it.

If I'm winning, I have to act like I'm not bored. If it's A tough match, I have to act like I'm having A good time. I'm a drama queen.

I decided I can't pay a person to rewind time, so I may as well get over it.

I'm a perfectionist. I'm pretty much insatiable. I feel there's so many things I can improve on.

You can be whatever size you are, and you can be beautiful both inside and out. We're always told what's beautiful and what's not, and that's not right.

My smile is my favorite part of my body. I think a smile can make your whole body.
