I mean, when I was young I could write all through the night and I loved to work late into the night. Now that I'm older I work really well in the early morning when your synapses are firing a little better. But I work at different times of the day.

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.

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."

There's been no poet, no great poet in the history of poetry who hasn't also been a great reader of poetry. This is sometimes distressing to my students when I tell them this.

So, some of the most difficult formal poems that I've written, say one sentence sonnets, I've been able to do those fairly quickly whereas some of the clearest, simplest lyrics that I've written have taken me the longest to get to the clarity of feeling that you're looking for.

And what I've found over time is that for me to write a poem that I think is worthy that I can live with, two things have to happen.

Reading poetry is an adventure in renewal, a creative act, a perpetual beginning, a rebirth of wonder.
