The Backlash Against Sheryl Sandberg Is Already Starting

Although Sheryl Sandberg's manifesto, Lean In, was just published Monday, it already is generating a torrent of debate -- much of it among female professionals who complain they feel left out of Sandberg's vision of success in the corporate world.

"The very blunt truth is that men still run the world," Sandberg, Facebook's Harvard-educated chief operating officer, said in an interview with 60 Minutes. "I'm not blaming women...but there is a lot more we can do." Sandberg, 43, has ignited controversy in part because she argues that women are held back their inner doubts and that they need to "lean in" to their careers, rather than worrying about how they'll juggle work and children. "Most leadership positions are held by men, so women don't expect to achieve them, and that becomes one of the reasons they don't."

So far, the backlash against Sandberg falls into three camps.

Being at the top still often means foregoing a 'life'
One of the most poignant critiques came from one of Wall Street's most successful women, Erin Callan, the former CFO of Lehman Brothers. In a candid essay for The New York Times published Sunday, Callan wrote about her regrets of keeping a "singular focus" on her career, saying it wrecked her marriage and led her to forego having children.
