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.

In adversity, you have to find motivation to continue and do well.

We can never learn too much of His will towards us, too much of His messages and His advice. The Bible is His word and its study gives at once the foundation for our faith and an inspiration to battle onward in the fight against the tempter.

I've found my calling with Twitter. It's all about the amount of interaction you do, and the traffic you move, and I'm really good at that. I keep going and going and going, and no one can believe that I can keep it up.

My real motivation came from my quest for music videos to have the equally soul-touching emotional resonance that straight music does. Honestly, I'm not sure they ever can.
