The fundamental problem with most businesses is that they’re governed by mediocre ideas,” said Bill O’Brien, the former CEO of Hanover Insurance, quoted in Presence: Human Purpose and the Field of the Future. O’Brien offers, as an example of a mediocre idea, the maximising of return on invested capital. “Mediocre ideas don’t uplift people. They don’t give them something they can tell their children about. They don’t create much meaning.”
