Ed Batista on becoming trapped by our mental models:
We construct our mental models out of the meaning we extract from experience, and there’s inevitably a loss of fidelity as we focus on certain aspects of an experience (while ignoring others), interpret that data, and then conceptualize it as a general principle. And the gap that exists between our mental models and reality will continually increase over time unless we compel ourselves to test our assumptions, gather new data and update our models—which requires consistent effort.
