Excellence is rare in this world, including the business world. You just won’t know it if you are relying on management interviews. I am not saying I don’t read (or listen to or watch) interviews of business leaders. I do. But I read them for the same reason I read articles on Brexit, running, films, and the latest Trump tantrum: to gossip with friends, to pass the time on a Sunday afternoon, and for general interest in our fascinating world. Not for investing.
