First Principles Thinking

Rebuild from what you actually believe, not a quote filed as someone else line.

Key Concept

• A saved quote is not a principle until you rebuild the claim in your own words.
• Level 1: Say the idea in your own words before you trust the bookmark, like rebuilding Lego from memory not the box.
• Level 2: First-principles thinking is like translating a recipe into ingredients you can shop for - rebuild the claim before the bookmark becomes doctrine.
• Level 3: Because borrowed language hides gaps, rebuilding exposes what you actually understand versus what you only bookmarked.
• Level 4: Explain the idea on a blank page without citing the source - the stumble marks the gap worth drilling next.
• Level 5: The tell - can you defend it without citing the source? If not, you do not own it yet; pairs with The Feynman Technique when teach-back is the rebuild move.
• The tell: can you defend it without citing the source? If not, you do not own it yet.
• You cannot explain, extend, or apply an idea you never rebuilt.

Examples

• I kept quoting parenting advice from a podcast until I wrote what I actually believe about bedtime - first principles was my own claim, not someone else's quote.
• The HOA kept adding signs about parking until a neighbor asked why people park wrong - turns out we needed one marked loading zone, not five new rules.
