And then in the morning the kids will come and we will go.

I believe the most important thing in life, the mere and unique purpose of it, is to keep going. Nothing else, but finding a reason to wake up every other morning and putting effort into things that are so insignificant and replacable, gives life a sense of meaning. Nothing is crucial to survive, while some people devote their lives to their children and can not imagine a life without them; childless people survive just as well by finding satisfaction in other things, such as their work. People live and die for opposing causes, never doubting the meaningfullness of their lives.

Everything in life is replacable and non-essential for survival. It is not the specific purposes that render our lives worth living but the fact that we can convince ourselves there is one.
