Dartmouth College business professor Sydney Finkelstein asked star performers across many industries, “Who is the best boss you’ve ever worked for?” They described driven, enigmatic, tireless “superbosses.” These leaders populate entire industries with the talented people they nurture. Finkelstein argues that a small number of bosses produce the great majority of the best talent – a sort of 80/20 rule of leadership. He doesn’t portray superbosses as always admirable. You might not like your superboss, and you won’t use the adjective “nice.” But you’ll do anything for that boss, who is someone you’ll never forget and will even come to love – in a way. Finkelstein sets the superboss bar fantastically high, and his investigation will teach leaders at all levels how to become a little more super.
