Hi, I am Olga, female, 40, programmer, mother of two. Got here from HPMoR. Can not as yet define myself as a rationalist, but I am working on it. Some rationality questions, used in real life conversations, have helped me to tackle some personal and even family issues. It felt great. In my "grown-up" role I am deeply concerned to bring up my kids with their thoughts process as undamaged as I possibly can and maybe even to balance some system-taught stupidity. I am at the start of my reading list on the matter, including LW sequences.
