How do you know when a poem is finished?
I think there are varying degrees of ‘finished’ when it comes to poetry. A poem will ask to be finished, or ask you to leave it alone.
I hold the (probably unpopular) opinion that there comes a definitive point when a poem is finished or is as close to complete as it will ever be. I find the idea that ‘a poem is never finished’ too sentimental, too romantic. There is definitely such a thing as ‘overworking’ the poem and there is definitely a point where the only thing the poem needs from the poet is for the poet to step away.
