He [Johnny Cash] was so fragile. We invaded Iraq in March, and he died in September. And because his health was so fragile, he couldn't take the controversy of making a public statement against the war. He knew that people were rabid. They attacked me mercilessly after I did the press conference with Musicians United to Win Without War. He knew that he couldn't tolerate that.

I am so sick of reading about another car bomb, another suicide bomber, another 10, 20, 30, 70, 100 people dead in a day, both Americans and Iraqis.

Think about all of the families where the father is a doctor and the son is a doctor or generations of coal miners. Why did they go into that line of work? Because that's what they were taught. Or was it in their genes? It's not an either/or question. It's both. I was inclined in that way. I was sensitive to music and poetry, and it was around me growing up.

I have a real worker-bee mentality. Just show up, just do it. Even if you feel like s--t and you think you're terrible and you'll never get better and it will never go anywhere, just show up and do it. And, eventually, something happens.

The thing that scares me most is the shift from serving the people to exercising power and with it, this attendant narcissism. Sarah Palin is a great example of someone that just stirs the pot for the sake of the attention.

As I started writing about loss and grief, I was taking what felt unmanageable and using my songwriting, my sense of poetry and discipline, to try and make it manageable.

I was sensitive to music and poetry, and it was around me growing up.
