The girls of girls' schools, the author believes, are a kind of Platonic Form of American girl, an ideal to which most of the rest of society, of the country's meritocratic system, aspires for their daughters, a reflection of one's deepest values. She believes girls all over the country, in all high schools, want The Dream. They want to achieve and succeed in major ways unheard of in the past. What the author finds worrisome about young women is that in the quest to develop talents and aspirations, they have carved for themselves a frightening new territory where there is no concept of enough. The chance to become anything has become an impulse to become everything. When counselors get together, especially those from girls' schools, they concur that their girls seem to have a mechanism that leaves them without sufficient boundaries. Girls just keep adding... and adding... expectations, creating an endless list of chores and goals. In this article, the author presents some of the symptoms she sees of girls at risk, threatened by unsustainable dreams, including hyper-selective college admission at the climax, symptoms of nearly impossible day-to-day existences. A wilderness of girl-children losing pieces of themselves each year to their own overdevelopment.
