My last short story attempt gave me great learning opportunities and lots of room for improvement (i.e., it was almost a total failure).
I have over a dozen developed plot lines for novel / novella length detective stories, but I wasn’t getting around to writing them. I figured stripping the detective part from a mystery plot would automatically create a short story. Reader feedback proved me wrong.
I tried this approach twice. One story had a developed main character with relatable motives and actions but a weak ending. The other had a weak opening, a character without motive, and a good last line. Unfortunately, I can’t merge the good parts into a respectable short story.
I signed up for an online short story class. Learning the basics will help. I also joined an online short story critique group. Reading short stories and learning the focus areas of critiques will help refine my writing craft.
