Optimist Day sounds pretty self-explanatory… always look on the bright side of life, right? But it’s actually an official celebration for members of Optimist International, which is made up of clubs that “participate in community service programs that are dedicated to bringing out the best in youth.”

Luckily the Optimist Clubs are happy to share International Optimist Day on the first Thursday in February. They encourage us to celebrate by volunteering and spreading optimistic messages.

If you’re volunteering, you are dealing with other volunteers. Check out SignUp.com and SignUpGenius for free tools to organize and track your volunteers.
