I’ve done and continue to do so many useless tasks.  I sometimes joke that I have attention surplus disorder because I have patience for so much menial work.  Over the years I’ve done repetitive factory work (fish, tank parts, clothing) which is so boring that you have to go into your mind or make the job a game to keep from going crazy.  Some of my creative work is also dull and repetitive, such as letterpress work.  But there is something comforting in knowing what the clearly defined task is and completing it.  The frustration for Sisyphus is the tease, always thinking that this will be the time when he succeeds.  It would be easier if he knew for certain that he was going to fail each time. Hope is the cruel part of his game.
