Arianna appeared on Southern California public television station KCET on Friday to discuss Sheryl Sandberg's new book, Lean In, on women and ambition.
She spoke about her own challenges finding work-life balance, and what it was like to raise children while pursuing a high-profile career.
"I definitely found myself feeling guilty," she said. "if you're a working mother, they take the baby out and put the guilt in."
She said that while women face many institutional and cultural barriers to achieving leadership roles, she also believes women hold themselves back with fear.
"I see it again and again, women themselves, listening to these voices inside our heads," she said. Those undermining voices, she explained, tell people they are not smart enough, pretty enough, good enough to do what they want to do.
"Men don't have these voices as strong and as dominant as women have," she said. "That's really the point Sheryl is making in her book. Don't let these voices of fear get in the way."
She also stressed the importance of "leaning back" -- taking time to look after yourself.
"Leaning back and recharging is also important because otherwise we forget the meaning of life, we forget what matters to us, and we forget that we need to renew ourselves if we are going to have a sustainable life."
