If anything, we haven't changed much since we [with Venuse Williams] were kids. We really are the same people.

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

My fridge is really just vegan: coconut water, Gatorade (my favorite!), cucumbers, mint, kale, vegetables, ginger, and wheat grass.

Will I have to explain to my daughter that her brother is gonna make more money doing the exact same job because he's a man? If they both played sports since they were three years old, they both worked just as hard, but because he's a boy, they're gonna give him more money? Like, how am I gonna explain that to her? In tennis we've had great pioneers that paved the way - including Venus [Williams], who fought so hard for Wimbledon to pay women the same prize money they pay men, and Billie Jean King, who is one of the main reasons Title IX exists.

I'm always learning new things.

I've never dated anybody. It's good to get experience under your belt but you should never get wild or go crazy. If I can't see myself with this person for life -- I can't be bothered. I can't waste my time. I have some really good men friends but I believe in no sex before marriage. No fornicating. Stuff like that. I really believe in that. I mean, I'm not perfect. It's hard to live by the Bible standards but I'm really comfortable with me.

My smile is my favorite part of my body. I think a smile can make your whole body. I want women to know that it's ok. That you can be whatever size you are and be beautiful inside and out.
