“There was a guy, Pete Kiewit in Omaha, who used to say he looked for three things in hiring people: integrity, intelligence and energy,” Buffett said. “If they didn’t have the first, the other two would kill them, because if they don’t have integrity, you want them dumb and lazy.”
It makes sense — if you can’t trust someone to act with integrity in a situation that demands it, then should they really be allowed anywhere near you or your brand?
