I like the “flexible commitment” idea.
Clearly there is an alternative to blind overconfidence and skittish lack of staying power in ideas. That alternative, I believe, is flexible commitment. We can be committed to a course of action at the same time that we’re open to modifying it. Military leaders know this well: you create a strategy, but few strategies survive the fog of war. You are always ready to modify the strategy based upon conditions on the ground.
