There is nothing more disheartening that endless futile labor or doing something you absolutely loathe or have a fundamental problem with. As you might recall, Sisyphus was condemned to an eternity of rolling a rock up a steep mountain incline only to have it roll back to the valley again once he got it to the top. On his way back down the mountain, he had to think about his existential position.
Looked at in another way, work is applied effort. It is what we put ourselves into…whatever we expend our energy on for the sake of accomplishing something. Work in this fundamental sense is not what we do for our living, but what we do with our living.
Happiness resides in activity, both physical and mental. It resides in doing things that one can take pride in doing well. Those who have missed the joy of work, of a job well done, have missed something very important.
All work can be done well or it can be done poorly. All work can be done cheerfully and with pride or grudgingly and with distaste. Whichever way we do it is really up to us. It is a matter of choice. There are no menial jobs. Only menial attitudes. In the theatre we say there are no small parts, only small actors. Our attitudes are up to us. A laborer is worthy of his hire.
As Sisyphus presses his face against the rock, each atom of the stone, each mineral flake of that night-filled mountain itself forms a world. The struggle itself towards the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.

There is joy to be found in work indeed. Someone said that hardwork is a prison sentence only if it has no meaning. I wonder did Sisyphus find meaning for his hard work?
