  1. First-Principles Thinking, Made Usable
    First-principles thinking means breaking a problem down to the fundamental truths you are sure of, then reasoning back up from those — instead of reasoning by analogy to “how it’s usually done.” Traceable to Aristotle and popularized in modern form by figures like Elon Musk, it is a reasoning discipline, not a tested intervention; its value is mechanistic — it strips out inherited assumptions.
  2. Deconstruct the problem to its fundamentals
    Break the problem into the few things you actually know to be true, with no inherited conclusions.
    First-Principles Thinking, Made Usable
  3. Reason up from the parts, not by analogy
    Build the solution from the fundamentals you kept, rather than copying an existing template.
    First-Principles Thinking, Made Usable
  4. Use Socratic questioning to test each belief
    Interrogate every claim with “how do I know this is true?” until only bedrock remains.
    First-Principles Thinking, Made Usable
  5. Cycle from concrete to abstract and back
    Start with a story, name the principle, then return to a new application.
    Concrete Examples: How to Make Abstract Ideas Stick
  6. Rebuild from fundamentals and stress-test it
    Reassemble a solution from verified parts, then attack it to find where it breaks.
    First-Principles Thinking, Made Usable
  7. Expose examples before naming the rule (inductive first)
    Present several cases before stating the principle; let the learner induce the pattern.

  8. Prioritize protecting primary resources above pursuing secondary ones
    When under threat, guard your most foundational resources first — health, key relationships, income — even at the cost of secondary gains.
    Conservation of Resources Theory, Made Practical
  9. Prioritize direct experience over inherited belief
    Test philosophical claims through personal practice rather than accepting them on authority.
    The Perennial Philosophy, Made Practical
  10. Occam’s Razor: Prefer the Simpler Explanation
    Occam’s Razor is the heuristic that, all else being equal, the explanation with fewer unnecessary assumptions is preferable. It does not guarantee correctness — the world is sometimes genuinely complex — but it guards against over-fitting, conspiracy thinking, and the cognitive overhead of maintaining elaborate theories.
