"The young student loves to be informal because he feels uncomfortable with his limited knowledge of social customs and because he still clings to an impromptu adolescent chumminess. He behaves strangely and defies conventions mainly because he is insecure – his great dreams and great ambitions and general aura of impending great greatness are not quite matched by circumstances (and never will be); he still has to work at places like Virgin Megastore and Starbucks. Hence, the need to flout rules to show that they must be wrong about him. (His influence is seen especially in the workplace, where business casual is the leading indicator of a sloppy, immature, indulgent business culture, which reached its lowest point in the 90s at dot-coms staffed by people who spent most of the day running up and down the halls playing tag.)" -Udolpho

This is a particularly good quote if you just got finished reading Nation of Rebels.
