The realization, this all is going to end one day, no matter how much we try to prevent it, inevitably, it ends. Everything we are: the hearth aches, the triumphs, the loves, the loses; all accomplishments, everything we are which becomes our unique singularity, our memories, legacy, everything that is erased by time, is worth. This is not a nihilistic realization: only one travel in this body, never to be repeated.
Reflecting in the mirror of life's fragility, we confront the absurd concept of eternity. We try and try to make sense of that immutable constant moment of the forever, but after all, it is just wasted time trying to find meaning knowing where there is none. Instead, don't be afraid to embrace the uncertainty, because we are remembered by the souls we touch, the good we do, and the love we give not by the lives we destroy.
