Stress & Sleep · Stoic philosophy
Worst-Case Rehearsal
A structured writing practice drawn from the Stoic premeditatio malorum — deliberately imagining a feared outcome in full detail, then mapping what you would actually do and what would remain. It works on the chronic background worries that keep circling without resolution, not acute crises. Most people find that a worry spelled out completely is less powerful than the same worry left vague.
Evidence basis
Stoic premeditatio malorum: Seneca, Letters to Lucilius; Marcus Aurelius, Meditations. Cognitive-behavioral imaginal exposure parallels: Beck, Rush, Shaw & Emery, Cognitive Therapy of Depression (1979); Clark & Ehlers, cognitive model of PTSD (2000). Worry postponement and written exposure for GAD: Borkovec & Roemer (1995). Values-clarification component: Hayes, Strosahl & Wilson, Acceptance and Commitment Therapy (1999).

The practice
Step by step
- 01
Sit at a table or desk with paper and pen, or an open document. Close the door if you can. This is not a quick task — give yourself the full time.
- 02
Write the worry at the top of the page as a plain declarative sentence: 'I am afraid that ___.' Name the specific outcome, not a category of dread.
- 03
Set a timer for four minutes and write the worst-case version of that outcome in concrete detail — what happens, when, to whom, what it looks like the day after.
- 04
Do not soften it or add silver linings yet. If you catch yourself hedging, cross it out and write the harder version. The point is full contact with the imagined event.
- 05
When the timer ends, stop writing and sit with what you wrote for about thirty seconds. Notice any physical tension without trying to change it.
- 06
Now start a second section headed 'What I would actually do.' Write the first practical step you would take if this outcome happened — not how you would feel, but what you would do.
- 07
Continue writing: who in your life would still be present, what resources or capacities you would still have, what options would remain open to you.
- 08
Write at least one thing the feared outcome cannot take from you — a skill, a relationship, a way of being in the world. Be specific; vague reassurances do not count.
- 09
Read both sections back. Notice whether the gap between the feared outcome and your actual capacity to respond is larger or smaller than it felt before you wrote.
- 10
In a third section, write one sentence about what this worry may be telling you about what you value. A fear of financial ruin points to something; name it plainly.
- 11
Close by writing one concrete action — something you could do this week — that addresses either the risk itself or your preparation for it. If no action is available, write that down too; accepting genuine uncertainty is its own response.
- 12
Put the pages away or close the document. Do not re-read today. The practice is complete.
Modifications
Variations
Compressed 5-minute version: Skip the values-clarification section (step 10). Write the feared outcome for two minutes, then spend three minutes on the 'what I would actually do' section only. End with the single concrete action.
Low-dexterity or vision-impaired version: Use voice-to-text dictation into a phone or computer rather than handwriting. Speak each section aloud as if explaining it to a trusted friend; the verbal externalization preserves the core mechanism.
Note
Do not use this practice during an acute crisis, in the immediate aftermath of a traumatic event, or during a period of active grief — the practice requires enough psychological distance to observe the feared outcome rather than re-live a real one. If writing the worst case triggers dissociation, a strong startle response, or distress that does not settle within a few minutes of stopping, discontinue and speak with a mental health clinician before returning to it. People with a history of health anxiety or OCD-spectrum rumination should consult a therapist before using imaginal exposure techniques independently, as unguided exposure can reinforce rather than reduce the anxiety loop. This practice surfaces material about mortality, financial ruin, and relationship loss — common concerns for adults in their 60s and beyond — and should not be done immediately before sleep if you are already experiencing insomnia.
