In an old interview with The Paris Review, author John Steinbeck discusses how he aims his craft toward one individual person instead of addressing a large anonymous audience.
Forget your generalized audience. In the first place, the nameless, faceless audience will scare you to death and in the second place, unlike the theater, it doesn’t exist. In writing, your audience is one single reader. I have found that sometimes it helps to pick out one person—a real person you know, or an imagined person and write to that one.
This has provided Steinbeck with a sense of freedom and a lack of self-consciousness when beginning a new project. Focusing on a specific individual not only provides direction, but creates unity throughout your work. On your next project, remember to ask: who you are creating for?
