We've probably all asked ourselves this before, right? I'm facing this question (again) right now. I have some short stories that were published in a local literature newsletter that were well-received and I was encouraged by the feedback. Any of them could be fleshed out into a novel, one of which I have started, but then the old question(s) enters my mind. Is the trope overdone? Is my angle original enough? Do I have enough to build the little universes with? What are some ways to put your stories in check that you've found successful?
