I am on a lot of writers’ groups. Not a ton, but a lot.
And frequently, people there post messages describing their writing process. Maybe it’s part of a humble-brag about how many words they’ve accomplished, or in connection with where they are in the stages of getting fro here to there, or they are trying to help another writer fix a problem or get ideas about resolutions.
And I’m kind of amazed at how analytical they all are. They have jargon. They have outlines and diagrams and backstories and charts and maps.
They have moods: they are “on the edge” of things, or “settling in” with the characters. They are putting together building blocks or developing themes, growing their suspense or delving into motivations.
I just throw a few characters into a cauldron and turn up the heat.
