Provision yourself with the materials of a small story that can be woven into your day’s writing. Find the story by trash picking an old newspaper or magazine. Small town circulars are especially good. If old papers aren’t on hand, you might remind yourself of an old fairy tale or fable, or quickly learn something about the person who named, invented, or otherwise was partly responsible for something meaningful to you (i.e. a medicine, a monument, a particular black hole).
After you’ve found and acquainted yourself with this small story, spend one page writing—whether freewritten prose or diagrammatic notebook scatter—trying to mine the story for something highly sensory that might give you a transition into this story—an adjacency like a particular high frequency of sound, or a particular shade of yellow. In this mining page, turn the sensory stuff over and over so that you have a repository of ways of getting that sensory thing into words or phrases.
You have now provisioned your provision with sensory hooks so that, when the moment arises in whatever you are writing today, your found story can make an entry via sensory similarity. It enters as aside, as sidebar, as digression, as occasion for rumination, or perhaps lifted away from its original context and gifted to your story’s action, woven seamlessly into the story’s unfolding events.
Even if nothing makes its way into anything else, this warmup has warmed up your attention to the sensory field that surrounds any given event and slightly expanded your day’s field of vision.
