Reach out to existing rationalists past and present, and start trying to develop semi-original rationality skills building on your personal strengths, and the sorts of things you pay attention to.

I got a lot out of sporadically talking with people in the rationality community over Skype and phone and the like, and there are a lot of really good autobiographies by fairly important people. There really is a lot of information in the community that just isn't on LW, or in most of the meetups.

Feel free to PM me if you're interested in emailing back and forth about this.
