I have a brief new essay up at The Story Prize Blog, "Why I Am Not a Poet". Here's a taste:
I care about words, structures, rhythms, resonances, patterns, allusions, borrowings, sentences, images, emotions, voices, dreams, realities, fears, anxieties, failures, yearnings, and much more, but I don't really care about telling stories. The story is a kind of vehicle, or maybe an excuse, or maybe an alibi. The conventions of the story can be followed and forsaken in ways that get me to the other things, the things I care about.
All of those things I care about are things common to poetry — some more common to poetry than to prose, I'd bet — and that is why I read poetry, but even though I read poetry, I write prose because I just don't know how to do those things unless I'm writing prose.
(I think I would rather be a poet, but I am not.)
