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.

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.

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.

It's not easy to part with the trophies. However, I do need to have some long-term financial security for those close to me.

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

I just hated to lose.

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