What do all great stories have in common?

The word “but.” Which is to say inexperienced or poor storytellers structure their material with the words “and” or “then.” So “They did this, and then they did that, and then they did this, and then they did that,” which produces an episodic structure that doesn’t build on anything, and there’s no relationship between what came before and what came after.

Without the surprise, without the twist, if you don’t pull the wool over the audience’s eyes, then it’s unlikely you’re going to be memorable. It’s precisely the fact that things are not what they seem that makes a story interesting.
