Debora Spar: Marissa Mayer Has 'Been Attacked Unfairly' (VIDEO)

Debora Spar has some wise words for all working women who are trying to "have it all": Don’t try.

The Barnard College president appeared on HuffPost Live on Friday, where she discussed her new book "Wonder Women: Sex, Power, and the Quest for Perfection" and the pressures that women face in today's society. Spar said she believes that powerful women, such as Yahoo! CEO Marissa Mayer, have been unfairly criticized when they don't speak out in favor of workplace flexibility.

"I think Marissa Mayer is an incredibly talented person -- I give her all the credit in the world -- but I think it’s also a bit interesting to watch her," Spar told host Alyona Minkovski. "She’s been attacked unfairly I think for not doing more to support more flexible policies in her workplace, not to speak out more on women’s issues -- and even though I might want her to speak out more on women’s issues, I think by asking her to do that, we are falling into the trap of always asking women to do more."

Spar, who is no stranger to juggling a family and a demanding career, is encouraging women to free themselves of the notion that they must do everything perfectly.

"I don’t think anyone has it all, I really don’t -- and I think that's so important to get out there," she said.
