“Unrelenting indecision, isolation, confusion and anxiety about working, relationships and direction is reported by people in their mid-twenties to early thirties who are usually urban, middle class and well-educated; those who should be able to capitalize on their youth, unparalleled freedom and free-for-all individuation. They can’t make any decisions, because they don’t know what they want, and they don’t know what they want because they don’t know who they are, and they don’t know who they are because they’re allowed to be anyone they want.” http://www.eyeweekly.com/print/article/55882
