Sometimes after you have critiqued and repaired according to all these guidelines, you finally reread the poem and discover it has lost its original freshness or that you have lost some of your initial passion for the subject or excitement for the poem. That's when it is time to go back and revisit the muse. I've been known to create up to 49 generations of a poem. It is unfortunate that most of us don't revise by hand now that we're composing on computer. Seeing a pile of revisions for a single poem is rather exhilerating and validating.
Some people argue that poems are like people, they're never DONE, they're always in process.
Some days I believe that and some days I don't. I do know there comes a time when we must let the poem go, like a healed bird, or like a child. Your poetry is to be treated, eventually, like the people in your life who you treat with respect. If you love this poem enough to be possessive and hypersensitive to any critiquing of it, you DO NOT love it enough. Set it free of this fog caused by a lack of focus.
