I was very competitive. I hated losing. No matter what, I had to win.
I was making comebacks every single year. That makes it difficult mentally. It causes a lot of stress.
I've had a lot of luck. If I didn't I'd be washing bottles in Russia.
Roger [Federer], he brought tennis... one level higher. Normally he toys with everybody. With all respect to other players, he does whatever he wants on the court against them. It's incredible what kind of game he can play.
I pay the bills, I pay for everything.
I've lived my life the way I wanted to, whether scaling the mountains, partying long into the night or having fun playing soccer.
