I tried. I would sit down and try to bullet point each of the main plot points, but I couldn't get it right. I had a good idea of how the story was supposed to go in my head. Putting it down in written form was impossible.
Eventually, I figured out the answer for me. I write what I call the short draft.
As I'm plotting out the story, I write out a sort of summary or synopsis. Kind of what I want to happen in the story. I can work on this for weeks (a couple, anyway) until I have a cohesive story. Some sections I sort of skip over, while others I write out in some detail. The thing can end up being about 6000 words.
It's not a novel by any means, but once I'm done with the thing, I have an idea of where I'm going. I then take that document and turn each paragraph into a bullet point. As I write my first draft, I check off paragraphs as I write them into the story.
So, I guess I do write an outline, sort of.
Then, somewhere around chapter 3, I find that I deviate from my short draft. I start to go off on weird tangents. I add characters. I take out scenes that I thought would work. I rearrange events.
Yeah, kind of like battle plans not surviving contact with the enemy, my "outline" doesn't survive contact with the actual writing.
Ah well. I think this still qualifies me as a plotter.
