" The world we imagine seems as real as the ones we’ve experienced. We suffuse the model with the emotional values of past realities. And in the thrall of that vision (call it “the plan,” writ large), we go forth and take action. If things don’t go according to the plan, revising such a robust model may be difficult. In an environment that has high objective hazards, the longer it takes to dislodge the imagined world in favor of the real one, the greater the risk. In nature, adaptation is important; the plan is not. It’s a Zen thing. We must plan. But we must be able to let go of the plan, too. "
