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.

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

I love designing dresses and tops.

Luck has nothing to do with it.

If I'm not playing well, I do get down on myself because I am a perfectionist. [So I need] someone who believes in me more than I believe in me, someone willing to work as hard as I work. I don't understand what no means or what failure means; I only understand what yes means and try again means.

I've never felt invincible. I've never used that word to describe me ever.

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