It often happens to me that I'll try to write a short story, get a bit stuck on it, and then try to work out some of the kinks in the ideas as poems, or vice versa (I tend to write narrative poems). I've gotten to some of my strongest pieces in both genres by pendulumming that way. They definitely feel like they serve each other, though once I get to a happy place with a piece I would usually rather burn the other version of it than ever share it ?
(Also, congrats to you on your acceptance, and to everyone else with acceptances today!!)
