One of the things that drives the writer is the desire to share a story, to get a reaction, to see if it pleases, to learn, in my own parlance, if it “works.” But the process of writing is, I think, a fluid process, during which time the work can, and indeed, should change, evolve, and become its own thing.
At a certain point, the writer must become attached to the story, not the idea of the story. The goal is to have a story with a life of its own, not the life of the writer. If you share the work prematurely, you risk squeezing it into a box, so to speak. That happens because a reader/listener will react—the lifted eyebrow, the “did you really mean to suggest…?” You’d have to be made of iron not to respond in some way.
While you do need an outside reaction—an editor, a great reader—let the work reach a point where it has its own soul. Leave it alone until it can speak for itself, otherwise someone else will change its language.
