“Joking around is part of my personality, just who I am.” — Novak Djokovic

I always try to adjust to the situation.

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.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.
