I think a good poem should have some inscrutable part. You can't quite explain it. The poem can only explain itself to a certain limit and at that point you enter into a little bit of mystery. That for me is the perfect poem: to begin in clarity and to end in mystery.
Billy CollinsI'm trying to write poems that involve beginning at a known place, and ending up at a slightly different place. I'm trying to take a little journey from one place to another, and it's usually from a realistic place, to a place in the imagination.
