Watch President Spar on Good Morning America, as she discusses why young women should stop trying to be perfect.

In the current issue of Glamour magazine, read an article from her forthcoming book, Wonder Women: Sex, Power, and the Quest for Perfection. An excerpt:

"It wasn't supposed to be this hard. Like many women, I grew up believing we were equal to men, that we could have sex whenever we wanted, children whenever we chose, and work wherever we desired. For years, as a professor at Harvard Business School, I was the only woman in a room of alpha men and still I always felt equal. And I was. Then five years ago I was offered the chance to become president of Barnard College. There was barely a man in sight, and the change gave me a front-row view of what women are thinking and feeling now. We have opportunities today—to choose our educations, careers, spouses—that would've stunned our grandmothers. But now we're dazed and confused by all the choices. Feminism was meant to remove a fixed set of expectations; instead, we now interpret it as a route to personal perfection. Because we can do anything, we feel as if we have to do everything."

President Spar’s book will be published in September 2013. Read more in Harvard Business Review and the Chronicle of Higher Education.
