Morgan Housel

Bio

Morgan Housel's central thesis is that financial outcomes are driven not by intelligence, knowledge, or technical skill but by behavior, temperament, and the ability to endure. His most important distinction is between getting wealthy and staying wealthy. Getting wealthy requires optimism, risk-taking, and putting yourself out there. Staying wealthy requires the opposite: humility, frugality, paranoia, and the acknowledgment that some of what you have gained was attributable to luck. The two skill sets are not just different but often contradictory, which is why many who achieve success lose it.
