1. It’s difficult to properly develop a larger number of characters in a short story, and it's hard for a reader to keep track of them.

A short story only needs three characters a protagonist, antagonist, and what is referred to as a wrench or relationship character. The reader needs someone to cheer on, someone to hate, and, occasionally, someone who serves to advance .

2. Again, every story needs a protagonist. The trick is to make the reader care about that character. There are a few techniques to strengthen the connection between your protagonist and the reader.

Give your main character a passion, hopefully one that will be shared by the reader. Give your character determination that brings them out of their comfort zone. Give your character a weakness, one that is only shared with the reader.

A glimpse into your character’s psyche is another good approach. This will make your character feel real and go on to draw in the reader.

3.Every short story needs to have a single point of conflict. As a rule, no more than one is required for a short story.

The character should have either a dilemma, a revelation, or be faced with a decision of some kind. Surrounding that conflict should be a good dose of tension. Conflict and tension keep readers engaged and invested in your story.

4. Don't restrict your readers to only the visual experience of your story. Transport them into your world by letting them touch, smell, taste and hear it. This is what we mean when we say, "Show, don't tell." Invite your readers to explore the full breadth of what your world has to offer, as if they were really there.
