I have lived my whole life with high intensity.

I have always tried to avoid regrets. Could I have done differently some things in my career? Maybe.

Don't think about being the number one in the world, try instead to get through today's program as well as you can. Then we will see whether one day you'll end up as number one or number 100.

I have no interest in becoming a tax exile and living somewhere I don't want to - I just want to be at home with my family.

I am afraid of a lot of things. A dog. I could be afraid of a dog that's upset, for example. And on the tennis courts, maybe on the outside I look fearless, but on the inside, I'm scared. There's not one player in the world who isn't nervous before matches. Especially important matches.

It is important to recognize the small successes.

I would like to believe there is a God, but I think it is better to say I'm not sure there is a God and live your life with kindness and respect for people than to say I know there is a God and then do bad things.
