Whenever I start a book, I make a very long outline. Not so much A, B, C, 1, 2, 3, 4, but really paragraph outline of the episodes that I want to cover in the book. And it’s before I know a lot. When I do that, it is what I, as a layperson, would want to know about, say, Franklin and Eleanor Roosevelt. Then what happens is, you get so deep into it, that after a while you’re off on a million tangents. And I always go back to the outline, because what it was in the outline, that I wanted to know as a layperson, is what the lay reader is probably going to want to know too. So it’s a nice reminder to yourself, if you’re getting so deep into something that really the reader is not going to care about at all.
