Joking around is part of my personality, just who I am.

Honestly, I'm not a big fan of baseball.

... the winner is the one who believes in victory more.

I always tried to win. I was as competitive as I am today.

Tennis players we're always playing in center courts that feel like arenas. And when we get on the court and the crowd cheers your name or salutes you - it's like you're a gladiator in the arena. And everyone is cheering - and you're fighting, you're screaming, during your strokes - it feels like you're an animal, fighting for your life.

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.

As a kid I was creative.
