Changing the world one glass slipper at a time

Every night when the prince has gone to bed, Cinderella runs a few errands.
Okay, perhaps not ERRANDS per se. But they are necessary tasks which must be completed in order to achieve a goal - in this case the happiness of her kingdom.
Every one she has helped calls her a superhero - but she prefers the title not to mentioned too loudly.
Regardless, every night she is changing the world one glass slipper at a time.
