"I don't think I would be where I am now in tennis without what she's done," Venus says. "For me to have this opportunity to make a living doing what I love is really all thanks to Billie."
"What I admire most about Billie is what she did not just for tennis, but what she did for all females. She opened the door for every woman athlete that's playing in any sport right now," Serena says. "Billie, you know I love you. Thank you so much for everything that you've done for me, for my sister, for all female athletes. You're a great person, and hopefully one day I can become a quarter of the woman that you are."
