I took a trip in 2004, a year after the war started in Iraq. I played music on the streets of Baghdad for Iraqi civilians. I'd also play for U.S. soldiers at night when they were off duty in the bars. Then I would talk to people, and I would film them and ask them about their life and the conflict.

I don't know if it's so grand that I can change the entire world, but I know that I can help one person. So that's the goal.

I went to Iraq because I wanted to see what one year of occupation had done to Iraqi society, and I went to the West Bank and Gaza Strip because I wanted to see what three generations of occupation had done to Palestinian society. I found a lot more hopelessness and despair in Palestine.

My greatest sense of accomplishment has come from having two amazing sons, but it's also a paradox in that the times when I felt like the biggest failure have been times when I felt like, as a parent, I wasn't making the right decisions or succeeding in the way that I should.

The same way you can see me sit at a table in a movie and be six different people, the mother and the uncle and all these different things, when I'm in the studio, I can do that, too. I'm not trying to be a recording artist and have a certain type of music for the radio.

I long for a life that explodes with meaning and is filled with adventure, wonder, risk, and danger. I long for a faith that is gloriously treacherous. I want to be with Jesus, not knowing whether to cry or laugh.

I learned to not separate writing, shooting, and editing, it's all sort of one big mess of creative output.

Like many other scientists who hold the Catholic faith, I see the Creator's plan and purpose fulfilled in our universe. I see a planet bursting with evolutionary possibilities, a continuing creation in which the Divine providence is manifest in every living thing. I see a science that tells us there is indeed a design to life.
