Preview — The Goal
⭕ The Goal: Warren Buffett skipped the entire dot-com boom — ridiculed for years — because tech was outside what he understood deeply. Then he didn't lose his shirt when it crashed, because the same rule that made him 'miss out' made him unsinkable. His model: everyone has a circle of competence — the domains where your knowledge is real, tested, and earned — and the size of the circle matters far less than KNOWING WHERE ITS EDGE IS. Most expensive mistakes aren't made by ignorant people; they're made by competent people operating confidently just outside their circle: the doctor picking stocks, the engineer doing his own legal contracts, anyone repeating something confidently that they absorbed from one podcast. The edge of your knowledge is where your money, reputation, and time go to die — if you can't see the edge.
