*America’s tennis sisters are more popular than ever, especially after winning in the Olympics.

Venus and Serena Williams appear on the cover of The New York Times Magazine with an accompanying feature story about their secrets to success, best times, career lows, and dealing with racism.

Serena shared a horrible dealing while at the Indian Wells masters in 2001, which lead to her boycotting the event indefinitely.

“They don’t like me. I don’t need to be there,” she said. “I thought, people like Martin Luther King Jr. boycotted things. And this is nothing on that level. Look at Muhammad Ali, he didn’t even play, he went to jail because he didn’t want to go to war. The least I can do is stand up for my people and not go there. That’s the very least I can do. It’s not even that hard of a decision. I get a vacation on those two weeks. It’s like the easiest decision of my career. They can penalize me to death, I’m never going back.”

Growing up was no walk in the park either.
