In the long poem, if there is a single governing image at the center, then anything can fit around it, meanwhile allowing for a lot of fragmentation and discontinuity on the periphery. Short poems, for me, are coherences, single instances on the periphery of a nonspecified center. I revise short poems sometimes for years, whereas, since there is no getting lost in the long poem, I engage whatever comes up in the moment and link it with its moment.
