I don't have emotions about a lot of things. I rarely get angry, I rarely cry. I guess I do get excited a lot, but I don't get sad and enormously happy. I think a lot of people who talk about all that crap are lying. Right now I'm just trying to maintain happiness — that's all I really care about. Anyway, when you're my age and your hormones are kicking in, there's not much besides sex that's on your mind.

Right now, our mother -- our mother -- all of our mothers, Mother Earth is hurting. And she needs a generation of thoughtful, caring and active kids like all of you to protect her for the future. You can help us win the battle to clean up our air, our water, our land, to protect our forests, our oceans and our wildlife.

When I was young I used to have this thing where I wanted to see everything I used to think 'How can I die without seeing every inch of this world?'

I always wanted to be an actor and I'd never dreamt that not only would I be able to do this for a living, but also on top of that I'd be able to choose and steer the course of my own career.

I will fly around the world doing good for the environment.

You can make history, or you will be vilified by it.

I've always kind of made sure to maintain the sense of who I am and never be mean or cruel or snotty to anyone. Because, at the end of the day, it's not going to help you last in the business, and who wants to be around someone like that? I don't want to turn into 'that guy.' That guy!
