The Pythagorean evening examination (Hadot’s version)

Before sleep, review the day in three questions: Where did I go wrong? What did I succeed at? What remains undone?

Why it works

Hadot traces the evening examination practice through Pythagorean communities and into Stoicism. The structured review prevents both self-criticism spirals (by including successes) and self-congratulation (by including failures and remaining tasks). The mechanism is not moral judgment but calibration: building an accurate self-model over time, which is what character development requires.

How to do it

1. Each evening, take five minutes for the three-question review.
2. Question 1: Where did I go wrong today? Name it specifically, without elaboration.
3. Question 2: Where did I succeed — act well, show up, do what I said? Name it specifically.
4. Question 3: What remains undone that I genuinely intend to do? Name the next action.
5. Close the review. Do not continue into rumination.

Evidence

Evening review practices have clinical support in CBT (thought records) and structured self-reflection literature; the three-question format balances self-correction with self-affirmation, preventing both distortion directions. (clinical)

The specific Pythagorean three-question format is reconstructed by Hadot; the component practices (error review, success acknowledgment) are separately supported but have not been studied in this exact combination.

Common mistake

Spending all the time on the failure question and glossing over the success question — which turns the evening review into self-punishment rather than calibration.
