What Is This?
Evening review is a short, structured self-examination done at the end of the day, before sleep. It isn’t free-form journaling about how the day felt. It’s a specific set of questions, asked in the same order, aimed at tracking your own character over time: what you got right, what you got wrong, and what you’d change.
Why Practice It?
Without a regular check-in, most people’s sense of their own conduct is vague and mostly self-flattering: “today was fine.” Evening review forces specificity. It’s much harder to lie to yourself about a concrete moment, “I snapped at my coworker over nothing at 3pm”, than about a general vibe. Over weeks, the same questions asked nightly start to reveal actual patterns: a habit that keeps recurring, a trigger that reliably sets you off, a specific kind of situation you keep handling badly.
Stoic Roots
Primary source
What bad habit of yours have you cured to-day? what vice have you checked? in what respect are you better?
Seneca describes this practice explicitly in On Anger, attributing it to the philosopher Sextius, who reviewed his entire day each night before sleep, asking exactly these questions. Seneca says he adopted the same habit himself, examining his day in full and holding himself to account for it “as a judge.” This is one of the most directly documented Stoic daily practices in the surviving sources, described in the philosophers’ own words rather than reconstructed from indirect evidence.
How to Do It
Go through today's events in order, without judging yet, just recalling what happened.
Ask: what bad habit did I resist or correct today?
Ask: where did I act worse than I know how to act, and what set that off?
Ask: what would I do differently if that moment happened again tomorrow?
Stop there. The point is honest review, not punishment; don't extend it into rumination.
When to Use It
At the end of the day, ideally at a consistent time, before you’re too tired to think clearly. Five to ten minutes is enough. It pairs naturally with Morning Reflection, Seneca and Epictetus both describe checking in at both ends of the day, not just one.
Example
You review today and land on a specific moment: you were curt with a friend who called at a bad time. You ask what set it off (you were already frustrated about something unrelated and took it out on the first person in front of you) and what you’d do differently (say “now’s not a great time, can I call you back” instead of being short with them). Nothing more needs to happen tonight. Tomorrow, you have a concrete thing to watch for.
Common mistake: letting evening review turn into replaying the day’s failures with self-criticism attached. Seneca’s own description is notably calm, he compares himself to a judge examining evidence, not a prosecutor building a case against himself. The goal is accurate information about your own conduct, not a nightly verdict on your worth.
