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 charity is in the business of helping firefighters in any way that we can. For instance, after 9/11 we were the second-fastest charity to raise and distribute money to the widows and surviving family members of the 343 firefighters who died that day.

Tonight, tonight we've reached a milestone in our nation's march toward a more perfect union: the first time that a major party has nominated a woman for president. Standing here, standing here as my mother's daughter, and my daughter's mother, I'm so happy this day has come.

I think of my films as not necessarily political but more moral. Between my father, my stepfather, and my mother - they all felt pretty passionately about the importance of standing up and doing the right thing, and none of them were suck-ups. What motivates me is usually abuse of power.
