Sounds like a setup for frustration, right? Why not just write something you want to, something a little easier? Why put yourself through so much trouble? Wilson offers an excellent rationale:
All good fictional story-telling involves a narrator successfully running an obstacle course. The characters have established attributes (stray outside them and they become inconsistent and the story uncompelling -- see Ayn Rand). The setting has given props, given time constraints, physical constraints, etc. Each scene has a role, a thing which must be accomplished, a useful contribution to the overall narrative (and the author needs to know what that micro-destination is beforehand). On top of this, the readers have expectations. If any kind of story-grip has been achieved, they will be racing ahead mentally, guessing at the ending, at the arrival, the resting point, projecting their own path through the obstacle course or the maze . . . and they will typically be disappointed in the book if they guess correctly. Outfox them.Read the whole thing. A little reflection reveals how very true this is. The stories that stick with us are often the ones that tie us in knots with a surprise ending -- or that shoot straight as an arrow to the conclusion while keeping us waiting for the twist that never comes.
