Had an idea for a short story yesterday that was somewhat similar to another short story I started several years ago (but was trying to find a way to finish). It's similar in theme (revenge) and characters... which made me worry a bit that it is *too* similar.
Even when characterization differentiates plenty between stories, do you ever worry that repeating a story's theme, outcome, or other element is a symptom of lack of range and/or originality? What do you do about it - write a story in a different genre? Do writing exercises? Take a break? Something else?
