People who dream of something bigger and better are good role models.

I can pretty much call anyone, whether at the White House, in a company or in the media. I have access, because of the silliness of the entertainment world and how people react to it. It gave me an enormous opportunity to do anything I really want to.

Community service has taught me all kinds of skills and increased my confidence. You go out there and think on your feet, work with others and create something from nothing. That's what life's all about.

The most important role models should and could be parents and teachers. But that said, once you're a teenager you've probably gotten as much of an example from your parents as you're going to.

We started a movement... to build character, citizenship and confidence in young people.

The money was good while it lasted. The best part was clearly that it changed my view of what's possible, as far as thinking how you can have an impact on a national level.

If you can get a teen leader in each sector of a student population, you can pull people in. Everybody wants to get involved, but most are too afraid. When they see a person they think is cool leading it, they're first to join.
