Look at pictures of me growing up. It wasn't always the way it is now. It was a bumpy road for me.

But my happiness in this world - my level of peace - is never going to be dictated by acting.

The Internet is a big place where a lot of people can voice their opinions, and my mother chooses to pick fights with random people from all over the world who don't have the nicest things to say about me.

I'm a big fan of working out on my own. I put my headphones on and I'm pretty good at self-motivating. At the end of the day, I enjoy it. Once I'm there and once I get going, I tend to love it, and I feel good.

I've been lucky enough - well, maybe unlucky enough - to have had a lot of friends who have had their ups and downs. And for an actor, that's good. Life experience in any regard is good. So I've seen a lot and I've had my own experiences.

I decided to make 'Captain America' because I realized I wasn't doing the film because it terrified me. You can't make decisions based on fear.

The comic book world is so dangerous, you know what I mean? You say one thing and people - they're ravenous - they are very opinionated fans. But they're great fans.
