Volunteer for an Event or Organization.
Any Event. Any Organization. There is always some organization needing volunteers.
Hear about an event or organization in the paper or on social media that sounds up your alley, give the organizers a call. Stay after your shift to participate in the fun.
Not all events and organizations are fun, but consider giving them a nod as well. They may even be more fulfilling.
Please be careful to vet the event or organization if it is not already widely known to your community.
