I'm itching to go to the school library and start picking up anything that catches my interest now that the the thirst to learn has been reawakened.

That's a dangerous idea! Books in the library that are more interesting than your textbooks tend to result in "waking up" four hours later to realize you've read an entire book on [interesting subject x] and are still no closer to researching [boring essay topic y].

Good luck though! Your classes do sound pretty interesting. Hopefully you can stay engaged.

I would love to do some sort of work which involved restructuring the education system.

I think that's a brilliant idea, and it really needs to be done. The "but then you wouldn't make any money!" people are pretty annoying, but you can ignore them.
