Sisyphus continued

Another question about Sisyphus.  What is the end game of the story? For him it was a punishment, but is the moral of the story to somehow get the boulder up and over the top, or is the moral to push each day? What would happen if the boulder got pushed over the top of the hill and a day off was earned? To become what we are meant to become maybe we are required to push on that boulder every day.  Wish I knew.  Sure seems easier just to leave the stupid boulder at the bottom of the hill!
