If you write a letter of resignation or something with an agenda, you're simply using a pen to record what you have thought out. In a poem, the pen is more like a flashlight, a Geiger counter, or one of those metal detectors that people walk around beaches with.

I try to write very fast. I don't revise very much. I write the poem in one sitting. Just let it rip. It's usually over in twenty to forty minutes. I'll go back and tinker with a word or two, change a line for some metrical reason weeks later, but I try to get the whole thing just done.

Poems, for me, begin as a social engagement. I want to establish a kind of sociability or even hospitality at the beginning of a poem. The title and the first few lines are a kind of welcome mat where I am inviting the reader inside.
