Don't know what you like to do? I'd get a job if I could working for Best Buy as one of their Geek Squad Careers - Geek Squad or something like that and then go to college in the evenings, online. I'd take some general education requirement type classes to get them out of the way and to figure out what interested you and then look into that.

Alternately, I would read some of this book: http://wishcraft.com and see if I could figure out what I wanted and then how to go about studying/working at it.
