adventures in juggling

The one upside of keeping works running in parallel is that you can switch between them when one is stymied.

And then you have a day when you know that this story has a character telling a story, so you have to pick one, and you're stymied; and that story has a problem in that you need to go back and put in the set-up for characters to do things, and you're stymied; and the other story has a scene where you aren't sure where you put it, and when you start to revise, you remember, and you have to revert your revisions because the location was wrong, and you're not sure how to handle the remembered location except that obviously you have to clarify if even you can't tell.
