You must work just to eat and to provide. You have to fight for survival and protection. You need to dig deep in order to grow your character. You must reach high to reach your potential.
This is life. It never changes. That is the essence of being alive.
Not so much to reach a goal, but to live a life. While you have this awareness of being alive, this is what will take up your time. No such thing as just “coasting along”.
Living in the moment implies an awareness of one’s life. Mindful of the work, fight, dig or reach in the here and now.
The whole idea is to fill the little time you have in this life with as much purpose as possible. That is the point of being alive. That is what it means to be human.
