As of just now, I have finished the "cycle" that I started a week ago, adding at least 200 words to every chapter of every story that I'm working on. This did not result in my having a huge burst of inspiration and making massive progress on any one story, but it did cause me to do a lot of useful thinking and, in some cases, additional outlining of stories, along with the writing.
I'm a big believer in the concept that a lot of our thinking goes on subconsciously. So it didn't surprise me that in the later parts of the cycle, I suddenly got ideas for things to add to or mention in stories I had worked on earlier in the cycle. I hope that will keep going for a bit.
In any case, now I'll go back to sort-of focusing on the things I most want to finish next: the next parts of "Cartooniverse" and "The Power Arcane." Whether those will actually be the next things I finish remains, as always, an open question.
