First-principles thinking means breaking a problem down to what you know is true and reasoning up from there — instead of copying what everyone already does. Examples:
What is first-principles thinking? Read the full idea →Instead of accepting the going price, ask what a rocket is actually made of (metal, fuel) and rebuild the cost from there.
Understanding why each step works lets you adapt freely, instead of blindly following instructions.
Asking 'why do we do it this way?' often reveals the original reason vanished years ago.
Build the price up from real costs and value delivered, not from 'what competitors charge.'
Master the handful of core principles and you can derive the rest — instead of memorising a thousand surface facts.
That's just how memory works. Lock first-principles thinking in with a 5-minute active-recall session — spaced repetition, no signup.
