Regardless whether you’re a Plantser (an Outliner) or a Pantser (one who writes by the seat of their pants)—I’m a combo, a PLAN-ANTSER…HA! Did I just coin a term?—Anyway, no matter how you approach your short (or long) story, I recommend a basic story structure, like the classic, 3-Act. Aristotle wrote that a tragedy, (a type of plot) should be divided into parts: a beginning, a middle, and an end. He also believed that the events of the 3-part-plot must somehow relate to one another as being either necessary or credible. And so, we have the 3-Act-Structure.
The 3-Act Story Structure (Thank you Aristotle)
TIP: Before you design your structure consider first, what is the profound change you want your character to experience by the end? Why? Because the answer to that question should fuel your story through all 3-acts, delivering theme, character arc, and a satisfying resolution.
Act 1: BEGINNING – Set up. Introduce your characters; establish the story world, theme and tone. Here, your protagonist should be called to action, due to some sort of crisis point (inciting incident) that shakes up their ordinary world and launches them into a new one.
Act 2: MIDDLE – Conflict. Avoid saggy middles by plunging the protagonist and allies deeper into even more difficulties and obstacles. Often things get worse and they need to re-group and get back on their feet, before things can get better.
Act 3: END – Resolution. This is where your main character(s) figures things out, and actually develops the courage, or a plan to face their demons, slay their dragons, and solve their problems. As a writer, you should always write towards a satisfying ending. That’s why I started with the TIP of knowing what you want your character to experience, their ARC, by the story’s end.
This is a typical story structure is a good starting point if you want to write short stories. I also do this for novel length stories as well. Smart guy, that Aristotle, he sure knew what he was talking about.
