I'm the type of writer who is variously known as a "discovery writer" or a "pantser." I get an idea, usually a beginning, middle, and end, then start writing.
This isn't necessarily bad for a short story, since it's much harder to write yourself into a corner in 5000 words than in 50,000 or more. It's a really bad plan for a novel, though. (I've learned this the hard way.)
So when I read the Writing Excuses transcript Brainstorming with Mary and the supplemental material, I thought I'd give that a shot, since it explains an actual process with examples. I'm not very good at learning without examples, so when someone says, "Outline your story!" I balk because I don't know how. All I remember is mandatory paper outlines for high school English.
Anyway. I'm writing a short story from an outline right now. It's maybe a little easier, since I already have guidelines for each scene, and I can still discover things while I'm writing. The first draft is kind of rough (duh), but this will mainly need tuning of the word choice and style kind, as opposed to fixing the plot. Probably. Which is a little different, and I like it.
After this, I guess it's time to outline a novel. I have one in mind, even.
