Is it possible that this is true and yet applies to only a small subset of people? On LinkedIn this comment got near universal negative response along the lines of "that's impossible." But when you read their titles, it was universally jobs people have to pay their bills and not mission driven work. Why is the correlation between people who change the world and working very hard so constant if it's impossible or false? How could studies show it's false for the typical person but almost universally trust of the most impactful people?
