stoic practice
At day's end, seated quietly, the practitioner reviews the day's events and their own reactions to them without self-condemnation, asking specifically which of today's troubles were within their control and which were not. Seneca describes doing this nightly as a settling of accounts with oneself. A companion technique, premeditatio malorum, involves briefly and deliberately imagining a feared outcome in advance precisely so it loses its unexamined power when it's only encountered as a surprise.
