The prerequisite for this is a healthy foundation of self belief. Young adults out there are getting hammered by messages that imply that they are fundamentally flawed and will never stack up.
The messages need to be questioned. Questioning authority, your peers and the society as a whole is an important step to develop a sense of self. It means you might be perceived as a rebel or immature at times. Sometimes you can't give a shit what other people think about you: I do not see that message being reinforced. I see vicious conformity among American youth.

That worked when gossip didn't travel farther than the next town.
Just when young people are given more viable ways to live than ever to pick from, they're given fewer chances than ever to start over if they choose unwisely. Are many narrow choices better than a few broad ones?
