Is it enough just to know how a story begins and ends? Or should there be a point where you cast it aside because you cannot fill in the middle? For example I have a story I've been working on for two years, I know exactly how it begins, and I know exactly how it ends. I've built the world for it, fleshed out the characters so that they are not one dimensional archetypes, yet I cannot fill in the middle of the plot. If the beginning is point A, and the end is point C, well I have had about four different variations of point B and had to cast them all aside because they just felt like useless padding. So I am wondering, should one cast aside a story even though they know how it begins and ends, and I don't mean just vague beginning and end, I have about 13,000 words of this thing written, all of which is pretty solid. It's just the middle is missing. If I didn't have to go through "Point B" I could almost submit this thing for publishing now. I'm just wondering, have any of you ever had to cast aside a story because you couldn't think of enough plot points to make it work?
