Life is a journey.
Every one of us is gifted a set amount of time on this earth, and we all must make the best of it before that time is up.
While none of us knows exactly how long we have, what is amazing is that per unit time, we all get the exact same amount every unit.
We all get different total amounts, but no one's hour is discernibly different from another person's hour. Yet, that is the only real similarity, as some people simply waste entire decades away, while others perform deeds in a few hours or even minutes that last for all of eternity!
Some people live life so unremarkably that their existence and non-existence is almost the same to others; while some literally change the course of history.
