Even earthquakes are the consequence of tensions built up over long spans of time, imperceptibly, incrementally. You don't notice the buildup, just the release. You see a sick person, an old person, a dying person, the sight sinks in, and somewhere down the road you change your life. In movies and novels, people change suddenly and permanently, which is convenient and dramatic but not much like life, where you gain distance on something, relapse, resolve, try again, and move along in stops, starts, and stutters. Change is mostly slow. In my life, there had been transformative events, and I'd had a few sudden illuminations and crises, crossed a rubicon or two, but mostly I'd had the incremental.
