Eliezer and others on LessWrong have authored a treasure trove of articles on using your brain more effectively. For a high level map of some "tracks" of articles elaborating common themes, check out http://wiki.lesswrong.com/wiki/Sequences
It's just about impossible to start if you're intent on reading the articles in order, however. Every article seems to link to some collection of other unread articles. I manually scraped them all a while back and came up with a rough graph order, although there are some circular loops (cycles).
