From another blogger (Monique at A Novel Quest) I've learned about Coursera. It's a listing of all the free courses you can take from Universities around the world. I know for people who want to get motivation to make a change in their life there's the persistent questions of "Where do I begin?" followed closely by "how?". Here's one of the many options you can try, Coursera. Dabble with some courses, see if it any of it ignites a little passion in you. Or you might try it and think, oh yeah, I still hate school. That's not for me. Either way, trying something new might be just the boost you needed to get going to what is right for you.
I've signed up for "Imagining Other Earths" from Princeton University. I'm SO excited from the intrudoctory email and video. It's not too late to join this one! I was already sold on it before the video started, but as he started talking about the final lessons of designing my own solar system I got pretty pumped. The instructor says it's light on the science and anyone can take this course.
