Have you heard of Dabble? They are a Chicago-based startup that organizes one-time classes on a variety of different topics, from fencing to blogging. Every class has the same flat fee--$20, and meets for two to three hours. There is no commitment to five class session, just one evening.
I read about them over the summer and thought it sounded like a brilliant idea. They announce new classes once a week and I've been meaning to sign up for something for awhile. Last week, I bit the bullet and signed up for a jump-start course on getting things accomplished in 2012. It seemed a fitting choice. I'll report back on how it goes!
