Many of the wars we see around the world start as domestic conflicts that are fueled by external forces and powers. My view is that we can help peace if we help communities transform from the inside, on their own terms.

For many child soldiers, war and violence are all they have ever known. If we don't take it upon ourselves to show them an alternative, then they're going to be soldiers forever, and they'll continue to be recruited and to participate in violence if another conflict starts five or 10 years down the road.

I've been trying to understand conflict and violence ever since I was a kid. You know. There were a few things that happened even on my block - the Black Panthers used to be right around the corner from where we were.

While it's easy for South Sudan to feel distant, the situation is all too real for the South Sudanese mothers choosing which child gets to eat tomorrow. This is a time when we must look outward together and declare that humanity has no borders - no one deserves to suffer like this, especially in a world of such abundance.

I see a trend here where the President seems to think his job is to count votes and then try to make a deal That's what we in legislatures do. Mr. Obama's job is to travel the country, fight for the values that he cares about.

There's going to be space travel at some point.

I really enjoy what I do, and who I'm with and where I am. Having said that, I'm not really a person of habit, because what I do in my job is travel around the world and play concerts to people, and occasionally do very weird things.

Be careful going in search of adventure - it's ridiculously easy to find.
