6) Long plot explanations aren't going to get it. Like, when something neat (horrible?) happened to one of the characters a real long time ago, and you really really want to tell us about it, you know? Don't.

10) At every turn, ask yourself if you're being gullible, dopey, pretentious, cloying, adolescent, Neanderthal, routine, dull, smarty-pants, clever, arty, etc. You don't want to be being these things.

21) If you write a sentence that isn't poignant, touching, funny, intriguing, inviting, etc., take it out before you finish the work. Don't just leave it there. Don't let anyone see it.
