9 Thinking Rituals You Can Steal From History's Greatest Minds
Main summary
Key takeaways
Key wellness, self-care, and productivity strategies (from historical “thinking rituals”)
1) Protect your time for deep thinking (create the right mental conditions)
System 1: “Space-time oasis” (John Cleese)
- Choose one problem and write it at the top of the page.
- Book 90 minutes with a visible start/end time (clear end is essential).
- Remove distractions: phone in another room, door closed.
- Expect “noise” (irrelevant thoughts) for the first ~30 minutes—sit still and let it pass.
- When you get the first answer, write it down and continue (don’t judge it as “too obvious”).
- Stop exactly when the alarm goes off.
- Reserve the next 90 minutes the following week for the same problem. Use successive sessions to uncover the real obstacle.
System 2: Time for big thoughts (Richard Hemming)
- Set one consistent weekly slot (same day/time) and protect it completely.
- Keep a page of 3–5 “big questions” you rarely have time to address.
- Each week: pick one question and either discuss with a colleague or write during the slot.
- End with a reflective sentence: “What would I do differently next week if this were true?”
- Example pattern: the “question” becomes actionable only after several weeks of repeated review.
2) Load the problem into the subconscious instead of forcing it in real time
System 3: “Hammock” (Rich Hickey)
- Write the problem in one sentence on one page.
- List:
- what you know
- what you don’t know
- Write constraints + a first rough sketch.
- Stop working and close the notebook (overnight; for big tasks, three nights).
- During downtime, capture emerging ideas under the sketch and allow your critical mind to evaluate them after.
System 4: Six notebooks and a bathtub (Agatha Christie)
- Place cheap notebooks around the house (or a note on your phone).
- Use the “recording” test: can you capture an idea in < 5 seconds, anywhere?
- When an idea comes: write it immediately (no organization needed).
- Pick one boring daily task and pair it with an open problem.
- During routine: no extra audio/input (no podcasts/audiobooks)—just the problem + routine.
- Once a month, reread notes and consolidate relevant ideas onto one page.
System 5: Solve the “stupid” version (Claude Shannon)
- Write the problem in one sentence.
- Strip away conditions until it becomes trivial (“eliminate everything except the essential”).
- Solve the trivial version.
- Add one condition back at a time, adjusting the solution—repeat until you reach the original problem.
- If stuck: rewrite using three different “dictionaries” (different metaphors/industry language) to see the essence differently.
3) Use writing to correct thinking (emotional regulation + better decisions)
System 6: The Golden Rule (Darwin)
- Create a page with your current belief at the top.
- Whenever you encounter contradictory facts/opinions, record them on the same day.
- Every two weeks: read the “objections/contradictions” page before the belief/plan page.
- If multiple entries point the same way (e.g., three entries), change the plan.
- Core principle: don’t rely on memory being fair—use writing as a “mechanical fuse.”
System 7: Unsent letter (Lincoln)
- When angry with someone:
- Write the full letter without editing (name the person; be complete).
- Do not send it—put it in an “unsent” folder.
- Wait 2–3 days.
- If action is still needed, write a shorter second version and send.
- Core principle: give anger a channel, then let time reduce the damage of overconfident emotions.
System 8: Weighing reliability (Ray Dalio)
- Before accepting advice, rate each person with two questions:
- Have they done it successfully at least three times?
- Can they explain the cause-and-effect (not just that it worked)?
- Use a weighted outcome:
- Two check marks = full weight
- One check mark = half weight
- No check marks = politely listen and move on
- Decide using weighted assessments, not loudness, proximity, or emotional closeness.
System 9: Morning rehearsal (Marcus Aurelius)
- Every morning, for the difficult people you expect to meet:
- write the person’s name
- write the behavior you expect
- write the response you will choose while calm
- Every evening: check off what actually went according to rehearsal.
- Example technique: decide a firm, non-escalating phrase in advance for recurring disrespectful comments—then use it as written.
