While learning from ones mistakes (i.e. past)
and planning (i.e. future) serve practical purposes, either can become
debilitating and ruinous if used to facilitate and maintain regret,
resentment compulsive expectations, or longing. Past for past's sake
and future for future's sake is quite unhealthy and unrealistic, however
much of a reality it seems for many. Just as working in an office environment all day is practical for the procurement of money (thus clothing, food, and shelter), living solely as such would invariably lead to some sort of social constraints, physiological dysfunction, and an eventual marked inefficiency in the overall performance of ones professional and extracurricular tasks. The affect of such behavior permeate modern values, conventions, and social practices; they are symptoms of an idealogical extreme. The point being that there is a purpose to such things, but only up until a certain point of preoccupation.
