Today's episode teaches first-principles thinking — Aristotle's idea, popularized by Elon Musk, that the sharpest decisions come from stripping a problem to what is genuinely, verifiably true and rebuilding from there rather than from habit or analogy. We look at Tesla's battery breakthrough and Amazon Prime to see the method in action, then land on one small question you can ask right now.

The one action for today: take a decision you're currently sitting on, write down the assumptions underneath it, and ask of each one — is this actually true, or is it inherited?

Key Topics: first-principles thinking, decision-making, mental models, problem solving, clarity, reasoning from evidence
