If you find yourself with some time on your hands this holiday season (or whenever), volunteer with Chicago Cares. The group organizes more than 100 volunteer events every month in a variety of issue areas from education to hunger to technology. Volunteer events are structured to work with the average person's schedule, so almost everything is scheduled after 5 on weekdays or during the day on weekends. And you can sign up for single events or ongoing projects. Combat the winter chill by doing something that'll make you all warm inside!
