Books
I wear glasses because as a child I would stay up late, covers pulled over my head, reading by the dim light of a dying flashlight. At least that's what an eye doctor told me when I was younger. Probably a load of crap, but I still love reading and I still often do it by poor light far later in the night than is reasonable.
I've always taken notes while reading, usually with a pen and paper, but sometimes as highlights in the Kindle. And of course since I have all this stuff in text files I thought might as well put it online. So here you have it, books I've read and things I've thought about them.
