I feel like this myth is my life. Not that I ticked off any ancient Greek gods (and especially not Zeus, never Zeus!), but I'm pushing the stone of achievement/happiness up a long mountain and just as I'm about to peak, and I'm feeling pretty darn good about the work I've done so far, I lose my grip and the stone falls back down to the bottom. When I get to the bottom, there are all these people walking past, thinking that I'm not even trying, not believing when I tell them I am.
And this continues for eternity.
