Sure, you likely knew things were changing, that the luster was wearing off the romance, but when did it finally change from decline to the end? Change, all change both good and bad, is a slow incremental process. You don’t just wake up one morning and find that you’re 30-pounds lighter (or heavier).
It is the realization that change has actually occurred that usually is abrupt, and that realization is always after the fact.
Some of us spend far too much time trying to measure our progress and the result it most often frustrating. Even worse, some of us lack confidence and need every minute scrap of achievement to fuel our perseverance. To these unfortunate souls, a minor setback or lack of measureable results can rob them of their momentum.
