I would say there are different kinds of poems. There are things that poets in the history of poetry hit upon when they're very young that can never be outdone and it's a remarkable, strange experience when you think of say Arthur Rimbaud who write poetry between the ages of 17 and 21 whose career was over by the time he was 22.

There's never been a culture without poetry in the history of the world. In every culture, in every language there is expressive play, expressive word play, there's language use to different purposes that we would call poetry.

Often you've read another poem that you think is so beautiful that you'd like to make something like that. And so you try to make a sonnet that works in a certain kind of way, or you try to make something that's songlike, or you create a refrain, or you love the way a poem works in two line stanzas and you try to do that.

That you write a phrase or you think of something and it seems to have a deeper charge because the title has to be some kind of marker, something setting out a space, creating a space for what's going to come.

I was once doing a question and answer period with the novelist Jane Smiley in a bookstore and someone asked us what our processes were and Jane said hers and then I said mine and Jane said, "Well, if I had a student like that I'd force him never to write like that again because you could never write a novel in the way that you write poetry."

The way to become a poet is to read poetry and to imitate what you read and to read passionately and widely and in as involved a way as you can.

I think it shapes it in very deep ways that you don't entirely understand. Rainer Maria Rilke said there are two inexhaustible sources for poetry. One is dreams, and the other is childhood. I think childhood is an inexhaustible source of your becoming who you will be and certain deep feelings are set inside of you.
