What's a good way to go about learning electronics that doesn't involve a class?

I can’t attend any kind of regularly scheduled class on account of my job’s rather fluid schedule, so I was thinking about kits or something.
My experience so far is limited to a simple circuit (first grade, 9v battery and a lightbulb), electromagnet (Grandma’s garage, wire, bolt, and battery) and a crystal diode (?) radio in Cub Scouts.
