then I'll remember what I once would have given for this moment

The great poem is always possible.
Think of Keats and his odes.
But we shouldn't have to be dying,

What I'm writing now is not
the great poem. After a few lines
I could tell. It may not even be

a particularly good poem, although
it's too early to decide about that.
Keep going, I say. See what happens.

But trying hard is one of the problems,
since it shows in the lines as a strain
or struggle that reminds the reader

too much of the writer, whereas
most readers want to listen alone.
The great poem, I think, will arrive

when I no longer care. Perhaps
I'll have abandoned art altogether,
and I won't even want to write

the poem down. But then I'll remember
what I once would have given
for this moment, and I'll go back

to my desk. And I'll write the poem
as though I were another person,
someone I will never be again.

[Lawrence Raab {1946- } 'The Great Poem', from Best American Poetry 2006]
