Overthinking is a loop, not a personality

Rumination repeats because it feels productive. Each pass over the problem produces the sensation of progress without the cost of action.

Interrupt the loop with a physical state change, then convert the thought into a single written decision with a deadline. Ambiguity is the fuel; specificity is the extinguisher.

Do this consistently and the loop weakens — not because you stopped caring, but because the brain stops predicting reward from the repetition.
