The first line is the DNA of the poem; the rest of the poem is constructed out of that first line. A lot of it has to do with tone because tone is the key signature for the poem. The basis of trust for a reader used to be meter and end-rhyme.

I hope the poem, as it goes on, gets more complicated, a little more demanding, a little more ambiguous or speculative, so that we're drifting away from the casual beginning of the poem into something a little more serious.

There's a lot of unconscious activity that goes on I think in the composition of a poem.

One of these days I'm-a make me a book out of you.

You, quote, find your voice, unquote, when you are able to invent this one character who resembles you, obviously, and probably is more like you than anyone else on earth, but is not the equivalent to you.

But tomorrow, dawn will come the way I picture her, barefoot and disheveled, standing outside my window in one of the fragile cotton dresses of the poor. She will look in at me with her thin arms extended, offering a handful of birdsong and a small cup of light.

There's this pet phrase about writing that is bandied around particularly in workshops about "finding your own voice as a poet", which I suppose means that you come out from under the direct influence of other poets and have perhaps found a way to combine those influences so that it appears to be your own voice.
