Hakunamatata (it means no worries)
Life is strewn with torment, misery and pain. Along the way are minute spurts of joy and happiness that fade instantly into nothing more than that hint of nostalgia when recalling 'happier times'. With so little joy to be found it is most essential to appreciate every moment of even the slightest hint of happiness. It is as well essential to dismiss the times of heartache and pain as part of the "thousand natural shocks that human flesh is heir to"(-W.Shakespeare)
To dwell on even minuets gone by is to miss the minutes in now and to miss minutes now is to lose more moments then and suddenly you awake, old, gray and alone as you ponder the years you squandered pondering the prior years.Do not squander by pondering but revel in life, and accept and forgive the "slings and arrows of outrageous fortune" so as not to miss the 'happier times'.
{a from memory rendition, not precise quote from W.Shakespeare)
tomorrow, tomorrow, tomorrow
creeps on this petty pace from day to day
to the last syllable of recorded time
and all our yesterdays have lighted fools
the way to dusty death
out out brief candle,
life is but a walking shadow,
a poor player who struts and fret
his hour upon the stage
and is heard no more
it is a tale told by an idiot
full of sound a fury
signifying nothing
