There's a lot of things in life that we don't know why they're coming exactly at this moment.

It's too many questions about what I'm going to do, why I'm retiring, and this and that. So I answer the same question, I don't know, a thousand times.

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.

Don't get too excited when I am winning, and don't get too depressed when I am losing. Just keep it cool.

I'm not fighting with myself.

I didn't change the world.

I could pose in fashion commercials as a high society star but politics is a new way of life.
