Johnny Cash was a rebel, not only just in the musical sense, but he was somebody who was for the people, and an advocate for labor, for workers, for prisoners, people who have been trapped by the criminal justice system.

I think right now is when we need to hear different voices coming out of all parts of the world. You can't just hear the politicians and the military leaders. You have to hear from the taxi drivers. You have to hear from the painters. You have to hear from the poets. You have to hear from the school teachers and the filmmakers and musicians.

Power to the peaceful!

It's also hard for me to understand growing up not knowing where I came from. I searched for my parents - I started when I was twenty; I found both my mother and my father when I was twenty-two. Trying to catch up on twenty-two years that we can never get back, trying to reconcile that - that's a hard thing for me.

My mother and father took me in and provided everything for me - the love, nurturing, basic necessities - to give me the space to grow wings, so that when I went out into the world, I could fly.

Playing on the streets of Iraq, or in Israel or the Gaza strip, I'd sing angry protest songs against war. People would say, 'Make us clap, make us dance, and laugh and sing.' It really made me think about the importance of happy music.

Don't settle for something that's not great. Don't feel like having a relationship that is not serving your needs is more important than having a relationship with yourself.
