I try to be careful not to do single concerts where I fly out, do my show, turn around and go home.

There was one tour where I thought, "If I can't get this feeling back of being excited to be on the stage, then I will quit." Because I have friends who have dialed it in and I watch their concerts and shake my head. I'm sure the audience can tell, too.

I have odometer readings, kids; all sorts of measurements of what I've been doing for the last 20 years. I get it. I get that it was a while ago.

Empires are doomed. They become more diffuse, more broke, demagogues rule, and so I was just pointing out some similarities between past empires and what's going on right now. They all have had to apply more and more harsh rhetoric of superiority and divine right to justify the building of hegemony.

We have evolved to understand that language of power that's taken too much.

I started going out with one of my managers and he really grew me up in a lot of ways. He introduced me not just to being a full-time traveler, which I was, but he was also really very interested in history and art and continued to open my eyes up to regional history; less splashy histories. He was interested in historical societies and stuff like that. He introduced me to a way of looking at the way communities form that is the foundation for the book that I've just finished writing that has to do with what I see as effective community-building wherever I've been traveling.

I'm becoming a professional nomad and enjoying that whole part of my life.
