We singer-songwriter people, we're used to getting up and doing our own thing in front of people, and we're it. We're the band, artist, writer, producer, front man. We're the whole thing. You develop, it's not smugness, but this self-reliance, that can limit your creativity. When you're willing and able to invite others into it, you wind up getting a piece of work that's bigger and better than anything you ever imagined it could be.

I had to really do some studying and examination of my own songwriting and I realized that, there's not a formula by any stretch of the imagination and aren't any rules, but there are principles. The first one is that art is a process, not a product. In fact, that holds true for damn near everything we do in life. The product is just something that happens. If you're faithful to the process, the product takes care of itself.

Years ago when I was in a cover band and we were playing dances, that was quite a different thing. You were there as part of an event. When you're a songwriter, you are the event. So it's a little bit of a different focus.

I say to my students that I can't teach them how to write a good song, but I can teach you how to write a better song. Talking about this idea of it being a process. By going back and not settling for something and find a way to step back from your songs-which is a very hard thing to do-but when you're stuck or you can't move forward, start doing some polishing.

Some things need to be a song. Some things need to be a play. Some things need to be a painting. Some things need to be-though I'd never be a choreographer-some things might ought to be a dance [laughs]. I've found that exploring an idea in different ways, it gives you different opportunities.

In the 80s, in the cover band I was in, we'd slip in original material. If you didn't say anything about it, people just didn't care. Sometimes they'd ask where that came from and you'd tell them, but you still had to play a bunch of Willie, Waylon, and Merle.

So I realized when I was successful in a piece, it was because I didn't abandon a notion early on what it ought to be, and I let it take me along. So I've had songs that started out as being about the environment and ended up being love songs and love songs that ended up being about the environment. I've had things that I thought would be a poem and realized that it was just too big for that. I've got to do something larger and it became a play. I wrote one poem that started a whole play.
