“[W]e tend to exist in a distracted present, where forces on the periphery are magnified and those immediately before us are ignored. Our ability to plan—much less follow through on it—is undermined by our need to be able to improvise our way through any number of external impacts that stand to derail us at any moment. Instead of finding a stable foothold in the here and now, we end up reacting to an ever-present assault of simultaneous impulses and commands.”
