I'm amazed that years after I stopped playing tennis, people still recognize me in restaurants and ask for my autograph.

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

It's tough when you're No. 1. You don't have any private life, you can't even walk anywhere. I think that was one reason why I lost my motivation to play tennis.

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.

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.

You have to find it. No one else can find it for you.
