  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. Rebuild from fundamentals and stress-test it
    Reassemble a solution from verified parts, then attack it to find where it breaks.

  3. 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
  4. Use Socratic questioning to test each belief
    Interrogate every claim with “how do I know this is true?” until only bedrock remains.

  5. Attempt to recall before studying new material
    Try to answer questions about material before you’ve studied it — the attempt, even when wrong, enhances retention of the correct answer when it comes.

  6. Reason up from the parts, not by analogy
    Build the solution from the fundamentals you kept, rather than copying an existing template.

  7. Sample inventive principles to generate solution directions
    Apply one or more of TRIZ’s 40 inventive principles as generative lenses, even without the full contradiction matrix.

  8. Challenge: systematically question why things are done the way they are
    Ask "Why must this be this way?" for each element of the problem — not to be contrarian, but to find which constraints are real.
    Lateral Thinking, Made Practical
  9. Provocation (PO): make a deliberately absurd statement to escape the pattern
    Prefix an impossible or absurd idea with "PO" to signal it is a provocation, not a proposal — then follow it to see what it unlocks.

  10. Train situational perception
    Before deciding, spend sixty seconds naming what kind of situation this actually is.
