When you're going through tough moments, you never know when you're going to have good moments.

A great tennis career is something that a 15-year-old normally doesn't have. I hope my example helps other teens believe they can accomplish things they never thought possible.

My main goal is to stay healthy because when you're injured you realise how lucky you are to have your health.

There's not many firsts in my career, as I have been a part of many tournaments and fortunate enough to win many.

My father was a photographer at the National Bureau of Standards. A self-educated man, he never finished high school, but in his career at the National Bureau of Standards, he made many useful inventions and eventually became chief of the Photographic Technology Section.

I'm a writer! If you work in an office, it dampens you. It makes you fit a routine. The effect of being a writer is not dissimilar to being long-term unemployed. And everyone knows that is not good for you.

I look forward to the end of all this money-making part of the career, to be truthful.

It's ironic that at age 32, at probably the greatest moment of my career, with The Godfather having such an enormous success, I wasn't even aware of it, because I was somewhere else under the deadline again.
