Here's a strange fact about maps: the most useful ones are the ones that leave things out. A subway map that showed every building, tree, and pothole would be useless — its accuracy would destroy its function. The Stoics had a version of this insight they called *katalepsis*, the idea that a firm mental grasp requires selection, not totality. But it's the philosopher Alfred North Whitehead who sharpens it into something more unsettling: he called the error of mistaking your selective model for the full territory the 'fallacy of misplaced concreteness.' When you're stuck on a decision — in a relationship, a project, a negotiation — you're almost never short on data. You're usually gripping the wrong map too tightly. Today, notice one moment when you treat your mental model as a description of reality rather than a tool you chose for a specific purpose. The question isn't whether your model is wrong. It's whether it's still serving you.

Which mental model are you currently using not because it's the best tool for the situation, but because you built it once and stopped questioning it?
