I meet people who say, "Girl, I watch every match, and I pray for you." I feel that energy and those prayers. Sometimes when I'm down on the court, in the back of my mind, I'm thinking, "They want me to win. Is there anything else I can give?" It encourages me to do better, to fight harder.

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

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.

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 proud to have opened [two] schools in Africa and one in Jamaica [through the Serena Williams Fund and its partners]. I was given a lot. I was given two parents. That's already starting above a lot of kids. And then I was given the opportunity to play tennis and parents who supported that. I feel I can give back.

You have to believe in yourself when no one else does.

The red kind of symbolizes a lot of things I do in Africa, along with a lot of the work, like the red laces. Everybody that buys a pair can pretty much save a life in Africa.
