Short Stories are a writer's friend. Have you ever found yourself involved in writing a story, and suddenly, a whole new cast of characters pops into your mind? The new plot is compelling, and you are tempted to drop the story you are working on for the new one. Or can you write both simultaneously? The best choice is to get your new ideas into a short story.Short stories are the foundation for longer stories. You now have something you can jump off from in the future. Get as many of your story ideas into shorts as you can quickly. If you mull over them too long, they become stagnant and fade from your mind. Build a catalog of shorts and keep them in the background until you can work them into novels or novellas.Writers often have multiple storylines in the back of their minds. New characters crowd in with already-developed ones. Utilize them by creating short stories. You will feel thankful that you did it in the future.
