Maria Popova spots this great comment from John Steinbeck.
If there is a magic in story writing and I am convinced there is, no one has ever been able to reduce it to a recipe that can be passed from one person to another. The formula seems to lie solely in the aching urge of the writer to convey something he feels important to the reader. If the writer has that urge, he may sometimes, but by no means always, find the way to do it.
I feel the same applies to vast swathes of human experience which business books reduce to apparently precise formulae.
