I am tired and not in good shape to think imaginatively. If I were more sensible, I would probably simply admit this and stop for today.
I tried a few approaches:
Looking over notes made today and other days
Reviewing posts from this day of the year for the past six years
(surprising how many are explicitly about meditation practices)
Made a new list of six possible themes
("Aging as a Spiritual Practice" - book by Lewis Richmond,
feeling good from a little weight lifting,
similarity between fake news themes and valuable brainstorming)
Anyhow, I have been trying but I am ready to stop.
