Start a Changepot

This is exactly as it sounds: a pot for change. If you don’t mind stopping in the middle of a room or the sidewalk—and maybe getting a few looks from passersby—pick up loose change that has fallen on the ground. Add your findings to the same jar and after a few months, see how much you have collected. If you’re strapped for cash, spend your findings on a nice meal for your family. If you are fairly stable financially, donate the money (anonymously) to a good cause.
