Other times you are lucky enough to learn about that, by looking from the distance to the hard way.
Anyway, it is never too late to realize that we have a single commitment:
To get the maximum out of our times, with our beloved ones. To avoid wasting time in pointless matters. To focus on the important aspects of everyday. To forget about tiny, silly issues which make us lose energy for no reason.
To fully appreciate the countless gifts we are given by the very fact of being alive.
(And in the case someone is wondering: definitely no, this post has nothing to do with inexistent superior beings. It has to do strictly with we humans and the indescribable joys of existing as a living being).
