President Obama inherited a broken country mired in two wars, a financial crisis, a mortgage mess and more than we all probably even know about and has in my opinion brought us back from the brink. But I still see my friends in no better shape and the gap widening.

I want to be a part of great things.

Kids clearly help center you because you can't impress your kids. People are like, "Oh, are they so excited because you're Ironman?" My kids couldn't care less. They like it when I hang out and play dad. I impress them by playing video games with them and doing well. Your kids humble you.

Once the steam engine went away and we started moving into burning fossil fuels - not just burning them, but everything we do with oil - we've been experiencing [these problems] at an accelerated rate. The scary end-game scenario is getting closer and closer, about what we're going to be able to do to sustain life on this planet as we have come to know it. And I think this is a very real possibility, that we could be dealing with conditions we have no idea how to wrestle with.

If you look up and no one who's around you has been around you for the past 20 years, and they're all new people, I think that's a problem.

It's important to keep the people who know you well around you. It helps center you.

I pray that our leaders stop pointing fingers and playing the blame game and seek a real solution for the good of the planet and all who inhabit it.
