I’m writing a book on various aspects of innovation and currently I’m doing some research on the different approaches you can take.
As part of this, I came across an interesting piece of advice from John Steinbeck (it’s one of 6 tips he gives on writing):
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.
