As a response to a post earlier today on Patrick Shawn Bagley's Bitter Water Blog, Sandra Seamans asked, "[D]oes there come a point where you can revise a story to death? [...] I'm not against revisions, just wondering how you know when to stop, how you know that you've gotten the story right."
I'm not certain it's possible to ever get a story "right." I revise until I've created a story that's "publishable." There's a point somewhere between "publishable" and "perfect" where the amount of effort necessary to achieve perfection becomes counter-productive financially. Even if you put in the extra effort, the story won't be any more publishable, the story won't earn any more money, and only a handful of readers will ever notice the difference.
Which, perhaps, leads to a discussion of the difference between an "artist" and a "craftsman." An artist might spend the extra time to achieve perfection, but only produce a new story every 19.3 months, while a craftsman might produce several stories in the same amount of time and never achieve perfection.
