Happyometer let's you measure just how happy you are. Choose a smiley face representing your mood for the day, and take some notes on what happenned that day to influence you. Then, choose a time period to rate how you score on the happiness meter.
When you think you're down, what better way is there to find out things aren't that bad after all?
Note: Chronically sad people probably shouldn't use Happyometer; it would probably be depressing. |
