PepsiCo CEO Indra Nooyi's comments last week on whether working women can have it all—a fulfilling career and family life—has reignited the debate on how best to balance career and family.
Economist Sylvia Ann Hewlett, CEO of Center for Talent Innovation and mother of four, thinks women can have it all but maybe not all at the same time.
"When you've been in the driver's seat all day, it's hard to come home at 7 p.m. and go from boss to parent. Women have to learn how to role shift effectively," she told CNBC's "Power Lunch."
"I think the women who opt out instead of leaning in are the ones who never learned how to transform their behavior from the boardroom to the living room each night."
Susan Patton, author of "Marry Smart," urges women to put family before career, because timing, like any successful endeavor, is everything.
"Ladies, work can wait, fertility won't, so spend your 20s landing a husband, not climbing the corporate ladder," she said.
