I have a notebook that I take notes from class in. But I keep forgetting it, so I have half of them on bits of paper. Then theres a huge scrap book that I stick my ournal that I type up nominally every week. Though mostly it happens a bit more sporadically, and I spend half of it saying, "And then... on the 23rd... this happened, but don't quote me, because it was a month ago... and I really can't remember."
Somehow I don't think it's quite as comprehensive as it's supposed to be.
