I was doing my daily routine of browsing Digg, and came across this wonderfully simple tool.  Joe’s Goals helps keep track of how your days are going, based on how much positive and negative stuff happens throughout each day.  You can keep yourself in check by allowing friends to see your status.

The application is really easy to figure out.  You can see and interact with an example just by going to the main page.
