I know that I have a previous ars poetica prompt, but I so love this poem: its depth, the lack of pretension, its humanity. I have written a few, but most of them are self-deprecating, one of them even titled arse poetica. But this poem is truly lovely.
For the first prompt, write your own ars poetica. Keep to a single image, unrelated to actual writing techniques and paraphernalia. Let it open up to your own life and hopes.
For the next prompt, use the line “Everywhere I go” as a ghostline and say what you have left of yourself.
