Serena Williams is arguably one of the greatest tennis players to ever play the game. She has more major titles than any active player and has won 23 Grand Slam singles titles- her most recent coming at the Australian Open when she was almost two months pregnant.

In this video, Serena discusses the people who doubted her as a tennis player because of her gender, her race, and how great her aspirations were. She says the only way to overcome the doubters is to have self-belief that what you want is possible.

"It doesn't matter how young or old you are or your age. You can achieve anything that you set your mind to...It requires discipline, hard work, determination, and most importantly it requires self-belief."

This quick video and worth the watch!
