Munger emphasized avoiding mistakes through inversion, asking what could go wrong before making a decision. This reduced downside risk and improved long term outcomes.
He insisted on a wide margin of safety when valuing businesses, buying only when the price offered room for error and intrinsic value was clearly higher.
