Five observations about some of the things Bill Belichick does that makes him successful: 1/ Inversion. Turn the question around, ask the opposite, figure out how to fail. 2/ Pattern recognition. Avoiding mistakes because you've learned your lesson is a powerful force. 3/ Culture. What the boss says and does. 4/ Counterfactuals. What else could have happened and why didn't it? 5/ Argue well. Focus on the truth and put egos and agendas aside.
