Write a story in a single word.
Select a sentence from your favorite novel. Tear out a page of your notebook or use an empty whiteboard to break down this sentence and find a deeper meaning, or possibly theorize what the author is trying to tell you (otherwise known as the theme). Then, write a story where you use this same theme.
Write a story about about a unifying place. Maybe this is a coffee shop where a regular group of writers share their work, or a church where folks go to practice their religion. Simply explore how these people are unified, and why.
