In our voyage through life, we encounter alot of experiences. Some are laced with undiluted excitement, some turn out very unpleasant while others are completely unbearable. These events form the crux of the popular maxim "the good, the bad and the ugly" which life is synonyms with, and is perceived by many as an inevitable cycle that must be completed by every homo-sapien that traverses the earth.
Depending on what side of the maxim life allocates to us per time, we react accordingly based on our level of emotional strength, innate acceptance of situations as they evolve (especially those that can't be readily changed), psychological stability, depth of our emotional intelligence and perhaps, our measure of faith in God.
Essentially, these events in spite of their coloration, sparks a plug in the cylinders of the engines situated in our minds. By way of comparison, "when a car engine comes up with one or more misfiring spark plug(s), it is only ideal that effective performance of the engine is inhibited until a replacement has been done as appropriate.
In the same vein, when we take out time to appraise our lives & the events that have played out therein, with emphasis on the 'mistakes, errors in judgement, failings resulting from indecision & setbacks amongst others which have come or is still being accompanied by very painful costs, we sometimes wish "LIFE COMES WITH RESET BUTTONS"
If the above is a possibility, It is certain a whole lot of people would select the option of pushing the reset button at specific intervals. This would basically eject all painfully unpleasant situations & ultimately, pave way for a fresh start on a fresh slate.
Unfortunately however, since the painful part of our lives can't be blotted away, we MUST learn not to only crave for the good times but also endeavor to embrace the unpleasantness that comes with life as a fundamental part of our biographies.
Overall, through think & thin, we must develop the courage to approach life with optimism & great hope that the bad times won't last forever & equally, work out strategies of correcting past mistakes that may threaten our happiness at present or in the near future.
