Boiling down rationality

Eliezer, if you only had 5 minutes to teach a human how to be rational, how would you do it? The answer has to be more or less self-contained so "read my posts on lw" is not valid. If you think that 5 minutes is not enough you may extend the time to a reasonable amount, but it should be doable in one day at maximum. Of course it would be nice if you actually performed the answer in the video. By perform I mean "Listen human, I will teach you to be rational now..."

EDIT: When I said perform I meant it as opposed to telling how to, so I would prefer Eliezer to actually teach rationality in 5 minutes instead of talking about how he would teach it.
