fwiw I relate muchly to your ADD post and I recently began doing something similar. Dividing novel concepts into novella series, (4/5) chapters each, and really committing to an outline method. I am a pantser at heart but it is clear I need a lot more structure to get anything done. The published ADD/ADHD novelists I know talk about using detailed outlines to stay on target.

Tor's novella revival convinced me that there is a market for my preferred length and I should go for it. So [x]yes to all this.
