`` if you insist on working , they will find some silly task to occupy your mind , like checking heaven 's streetlamps , to be sure that every light is absolutely pure ; or making manuscripts of holy screeds that no one but the penman ever reads ; or keeping careful track of all mistakes some mortal , living on the surface , makes , to use as evidence against him , when he comes to judgment , from the world of men ; or finding make-work jobs for others , who feel just as useless and as bored as you .
