When expectations are not met within an anticipated time frame, worries pour in to occupy the vacuum. For most part, anticipations have Poisson distributions which are tilted in the direction of increased worry! Empirically, modes of such anticipatory curves reside increasingly towards the tail of these distributions. This is partially due to our natural predisposition to overestimate the expected timing (mean of Poisson-like anticipatory probability distributions) of occurrence of events that are of grave importance to us.
Engaging in alternative activities while anticipating future events can effectively provide the necessary adjustment to mean. One of such activities is writing!
