I've just done a commercial in the U.S. in which I talk about stocks, shares and bonds. Everyone is amazed. They ask me: 'You really know about that stuff or did you just learn it for the commercial?' I tell them I wouldn't do it unless I understood and had an interest.

At 16, 17, you have no fear. You don't think or analyze. You just play on automatic. You can get smarter as you get older, but in sports you can be too smart, you know?

I don't know what better teenage life you could get than going around the world doing what you love to do.

Boyfriends have to understand me and my needs. They have to know what I want out of my life and about my strict regime. I go to bed at 10pm and not later. I separate my professional and private lives.

Like any young person, I do what I want.

Boyfriends have to understand my needs. I shower four times a day.

I believe in commitment. I believe in being open and trusting each other and respecting each other completely.
