(Excerpt from A Few Things I’m Pretty Sure About by Morgan Housel)
An engineer can have a successful career knowing nothing other than engineering. Same for a chemist, meteorologist, or radiologist. Business and investing don’t work like that. They’re a little math, a little accounting, a little sociology, a little psychology, a few parts marketing, law, politics, game theory, history, statistics, biology, and public relations. That doesn’t make them harder than other fields; just more uncertain, prone to change, and with fewer experts.
