When I started writing, like many others, I'd come up with a story, keep at it for a while, and then lose interest and start something new. They were always long, novel-length ideas. Finally I kept going with one, and years later, here I am writing its third draft. I've heard it's good for a novel writer to get some short stories out there, to start making a name for themselves and be more likely to be picked up by a publisher. For that reason, and to have smaller writing projects going so that I can write new stuff (it's tiring editing all the time), I want to start writing more short stories. My problem is that every time I come up with a new idea, they tend to be long stories, much too long to be considered a "short story." Maybe this is because I read a lot of novels, and not many short stories, but I feel like I don't have a good grasp of how to come up with one. For those of you who write short stories: do you start with a scene? a character? a theme? What's the best way to go about developing a short story?
