“the third villain of decision making: short-term emotion. When we’ve got a difficult decision to make, our feelings churn. We replay the same arguments in our head. We agonize about our circumstances. We change our minds from day to day. If our decision was represented on a spreadsheet, none of the numbers would be changing—there’s no new information being added—but it doesn’t feel that way in our heads. We have kicked up so much dust that we can’t see the way forward. In those moments, what we need most is perspective.”
