Somehow, that line just has a brilliant ring of truth to it: Once a hacker, always a hacker. And it's probably right. You can't go back to a life of normalcy after experiencing the exhilaration of hacking away at something for hours on end and finally getting it. What you can do, though, is apply your mind to the social system - as you said, hack it.

A lot of nerds and geeks (the ones I know at least) are unpopular not because they're unpleasant people (they aren't), but because they don't understand how the social system works, what you're allowed to say and what you aren't (and when). If you just watch people talking around you you can easily notice what annoys people or causes them to end the conversation, and avoid doing it. If you just apply your mind to everyday life, being involved in your surrounding culture really isn't that hard.
