I had a great tennis career. I have no regrets. But to find peace with yourself, and to finally be with your family - I'm probably the happiest guy in the world.

I have a great family, great kids. I have practically everything, you know? Sometimes I have to pinch myself. It's really true: Life starts at 50.

Tennis is a traditional game. A big sport like tennis does not need too many changes. The game has become too fast, there are hardly any long, interesting rallies these days. So maybe slowing down the courts could help. But you can't really stop a sport from evolving.

When I retired from tennis I wanted to do other things with my life.

I'm an actor who plays an intriguing character, not a political pundit.

If you're afraid of losing, then you daren't win.

As tennis players, we work and we sacrifice many things. To lose, that's not a happy thing - I mean sure, I was disappointed. You have to come back strong. But to win the last point in a grand slam tournament, that's the most beautiful and most satisfying feeling you can get as a tennis player. It's worth it.
