You're writing such a great story, or novel, chapter, tale, vignette, allegory and suddenly you think, crap, what comes next?
Well, you don't want to just continue haphazardly and risk it being completely bad, no matter what some artistic-types preach about just getting it out there on the page. Because well, let's face it, either you're drawing a complete blank or you're a perfectionist. At the same time you like the idea you had, and you really don't want to abandon it. What do you do? Where do you go next? How do you get unstuck? These are questions that bother a lot of writers.
