Make something that catches runaway thoughts before they snowball into a whole haunted house.
Not a journal or a planner. Something stranger than that.
Maybe it's a net made of moonlight. A little box with breathing holes. A jar that only opens when the thought's ready to come out. A machine that sorts your thoughts into "urgent," "not mine," and "absolutely not today."
Yours can be useful, magical, ridiculous, or weirdly specific. No wrong answer here.
Make it however you make things. Sketch it, paint it, collage it, build it, or just describe it in words. Give it a name if one comes to you. Tell us what kind of thoughts it catches.
Then drop it in the comments!
