"You need ... a board of directors ... who are very smart and strong-willed (people), who will argue with (you) as opposed to just (you) doing whatever it is (you were) going to do on their own. Most people need some forcing function where they're forced to fully think things through. (Where) they're forced to do all the work, and they're forced to ... defend it. And if they don't do that, it turns into complacency and laziness. At some point, it turns into arrogance, and it becomes very destructive. And then you stop being effective."
