1. I'm 17, a senior in high school.
2. I read a lot of nonfiction on my own when i have time, but lately I almost never have time. I've also learned a ton from doing competitive debate, though I'm not sure it's made me a better rationalist - I'm planning a post on this after I finish applying to college.
3. My family and friends tolerate my interest in rationality, and say "that's really cool!" whenever I explain things, but I haven't been able to convince them to read the Sequences or even the occasional post. My best friend learned Bayesian statistics for science fair and loves philosophy and debate - he'd be a fantastic rationalist if he wasn't Catholic. I'm working on that.
4. I take seriously the argument for giving what we can, and intend to go into a high earning career so I can donate what I can to charity (probably x-risk reduction). I haven't mentioned this before on LessWrong, because without a concrete plan for how to achieve it it seems like an applause light. I would love to talk with someone (CarlShulman?) about how best to do this, because I'm really not sure.
5. Nope. I learn well in an academic environment, and I still have a lot to learn.

As for the other things you suggest in your post: there are no meetups where I live, and I would love to just talk with rationalists occasionally. I've read all the Sequences, though I still have trouble with the quantum physics one, and I would also be interested in sharing tips on getting the most out of high school.
