The dichotomy of control
Sort every situation into what is up to you (judgments, choices, effort) and what is not (outcomes, others, the past).
Why it works
Most distress comes from spending emotional energy on things you cannot move — other people, results, the past. By forcing an explicit sort, you redirect effort to the only lever you actually hold: your own response. This is also a cognitive reappraisal move — it reframes a threat ("this is happening to me") as a bounded problem ("here is my part of it").
How to do it
- Name the thing troubling you in one sentence.
- Split it into two columns: what is genuinely in my control here, and what is not.
- Move all your attention and action to the first column; deliberately release the second.
Evidence
The control/appraisal distinction is the conceptual seed of cognitive behavioral therapy, whose founders explicitly credited the Stoics. CBT’s reappraisal techniques are among the best-supported in clinical psychology. (clinical)
The clinical evidence is for modern CBT reappraisal, not for the ancient maxim as stated. Treat the lineage as real but the specific framing as philosophical.
Common mistake
Mislabeling outcomes you influence (a job interview, a relationship) as fully "in your control", then crashing when they don’t go your way. Only the effort is yours.

More practices for Stoicism, as a Set of Practices
- Negative visualization (premeditatio malorum)
Briefly imagine losing what you have, so you stop taking it for granted and brace for setbacks.
- The view from above
Zoom out — picture your situation from high above, in the scale of the city, the world, and time.
- Voluntary discomfort
Periodically choose mild hardship — cold, hunger, plain food, going without — to train resilience and reduce fear of loss.
- Stoic journaling
Write to examine your judgments — morning to set intentions, evening to review how you actually responded.
- Memento mori
Keep death in view — not morbidly, but as a clarifier of what actually matters now.
