Serena Williams Opened Up About the Wage Gap to Glamour

"Who says that your thirties is when you’re supposed to be done? I would like to know who made that rule! I was talking to my mom one time, like, ‘Gosh, I’m 30.’ And she’s like, ‘In your thirties you’re even stronger than in your twenties.’ I didn’t believe her, but I have played better in my thirties. And I played pretty well in my twenties, don’t get me wrong! But my consistency is better, my momentum is better, my wins are quicker."
