Rewriting and "Time"

Two days ago I received a letter from a very nice editor asking that I rewrite and tighten the opening of the story (a reprint) I submitted to his magazine. He likes the story but the opening feels fat. No disagreement.

The story was one of the first I wrote and sold a long time ago. I'm a different writer now than I was then. Hopefully a better one. I would have written it differently today. But ... I literally don't have the time right now. I'm in the middle of a new screenplay and my writing partner and I are waiting for the rewrite notes from the production company on The Nest. I also have a full-time restaurant management job (gotta pay those pesky bills that crop up every month). I had to tell him "no" for the time being. Hated doing that but I had to. Short stories, like screenplays and novels and poems, take time and concentration. At least for me it does. I can't whip things out anymore. I agonize over finding the right word then the right phrase. I polish dialogue and characterizations. I want every piece I do to be the best it can be. Shoot. Anyway, back to work.
