When I write, I tend to simply let a story flow.
This means a lot more editing after-the-fact. One of the difficulties is that I will drop a character into a story without any character background. So, I have work to do establishing character backgrounds. Lots of people are organized enough to set up backgrounds for characters beforehand. I wish I could write that way.
On the upside, there are date generators out there, and I have gotten into the habit of tagging dates while I write scenes, so I know when events occur during the first draft of the book. It helps me set my fictional locations into the real world. So, my first project over the next week or so is to list the cast of characters in the books I’ve already written.
