My sense of a poem - my notion of how you revise - is: you get yourself into a state where what you are intensely conscious of is not why you wrote it or how you wrote it, but what you wrote.

I started listening to music when I wrote when I had three sons at home.

The irony is, going to work every day became the subject of probably my best poetry.

I realized poetry's the thing that I can do 'cause I can stick at it and work with tremendous intensity.

Back then, I couldn't have left a poem a year and gone back to it.

My father died when I was five, but I grew up in a strong family.

But most commonly, it's one poem that I work on with a lot of intensity.
