I seem to alternate years of not finding a publisher with years of better luck. My routine is the same with either: write a short story a week (I’ve nearly finished a sequence of 36 stories taking place on successive days); send rejected stories out to another publisher; query agents for a novel; and revise a 3/4 done novel, novella (usually a past year’s National Novel Writing Month project), or first draft of a short story or script — all of which must be kept in continuity with each other.
I used to think when a favorite writer didn’t have anything new that they were either writing a novel or taking time off. Most writers I know work steadily, all the time, and there’s a portion of luck in appears in print/on screens and when. A writer is someone who writes: I keep at it (and all the secretarial work that goes with finding publication) until my luck changes.
