Sisyphus and prayer

In Greek mythology there is a story of Sisyphus. Sisyphus dies, and goes to Hades where he has to push a boulder up a hill before he can go to the land of bliss, but just as the Sisyphus reaches the top of the hill, the boulder slips and rolls back to the bottom, so he has to do it over and over again.
This story came to mind yesterday as I was carting bricks around church property for the third time, and it would be easy to feel like we are being treated like sisyphus. We are constantly being asked to do the same job multiple times either because they need something moved, or we weren't told about a step part way through the job. so the job get's done over and over and over again.
But as I thought about the repetitiveness of the tasks that we are given, I realised that it wasn't pointless doing the same job over and over again. Doing the same job over and over again creates repetition the same way monks recite scriptures in latin over and over again. IT allows allows my mind to wander and for me to contemplate and work out with God my theology, my insterests, my beliefs, my feelings, my calling and my very existence.
Currently God's working out my calling. Yesterday during brick moving, God reminded me of a promise that I had forgotten from years ago that he had made me. He reminded me that my education will be in pastoral ministry because it's going to prepare me for what he has planned for me, but that full time pastoral ministry as I see it, preaching in a church every sunday, isn't what he's calling me to. I had forgotten this, but he reminded me. I still don't know what the call is for me, so I guess I'll have to dig some holes or something.
I'm still not sure what he's going to with my life, I guess I'll just dig some more holes
