what mr kaufman says is correct, however i believe cutie understands this and is exactly the point she is confused about.
ill restate her question if i may:
how can each person in the world believe that everything in the world depends on him alone? this is a self-contradiction. you might say well of course it cant be true but one should pretend that this is so, nevertheless, as a stimulus to Avodah. could be but i believe the inyon is much deeper than that.
