We all have I believe...
(It's just a link to a C.G.P. Grey blog post. Read it, it's really interesting stuff.)
New quirk for a list of things: I am obsessed with the accumulation of knowledge.
Actually it's more of an obsession with being right, but it kinda for me is the same thing? IDK.
So like, I just conditioned myself, accidentally of course, over time to be afraid of being wrong and doing wrong. It has lead me to do really in-depth research of a lot of topics and become really knowledgeable about them. (Starting like, maybe 9 years ago) That's not to say I don't find most of what I'm researching interesting, because if it wasn't I would stop looking stuff up, but I think it's the driving factor behind my comprehensive knowledge of things.
