I enjoy learning, but on my own terms and at my own pace. That why I disliked most aspects of formal education. Then along comes OCW.
At this stage of my ER life I could care less about diplomas, certificates, credits, etc. I just want to learn about things that interest me without getting in the car and driving someplace every Tu/Th 7:15 - 9:22 for a few hundred bucks being bored stiff :P
So now I'm taking Architecture. I get everything I need FOR FREE even a discussion group (my nickname will be Art Vandalay).
Additionally, anyone going back to work (not me!) can tell a prospective employer about completed studies relevent to the job. You don't need a degree in Spanish to demonstrate profiency. Habla? Check it out!
