When I was younger, I was always obsessed with nails.

I'm a real extrovert, but when I'm round someone new, I'm super shy.

I've always been a fighter and I've always fought through things my whole life.

I'm totally human.

Tennis is my job, but it's not my life.

I've always considered myself the best and the top. I never considered that I was out of it.

Someone like Billie Jean King is completely my idol.

Hopefully, we can build a rivalry and we'll be able to do this a lot. Make a legacy, then retire champions.

If you can keep playing tennis when somebody is shooting a gun down the street, that's concentration.

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.

I am not a robot. I have a heart and I bleed.

I don't know if I've had my share of drama, but I've definitely had my share of hard times.

All my life I'd woken up to tennis, tennis, tennis. Even if I don't go to practise, I'm thinking about it all day.

Tennis just a game, family is forever.

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

If anything, you know, I think losing makes me even more motivated.

I love who I am, and I encourage other people to love and embrace who they are. But it definitely wasn't easy - it took me a while.

Luck has nothing to do with it, because I have spent many, many hours, countless hours, on the court working for my one moment in time, not knowing when it would come.

No one likes getting their nails done more than I do.

Everyone's dream can come true if you just stick to it and work hard.

I'm not used to crying. It's a little difficult. All my life I've had to fight. It's just another fight I'm going to have to learn how to win, that's all. I'm just going to have to keep smiling.

I'm an athlete and I'm black, and a lot of black athletes go broke. I do not want to become a statistic, so maybe I overcompensate. But I'm paranoid. Oprah told me a long time ago, 'You sign every check. Never let anyone sign any checks.'
