My goal is very clear, and I wrote about it in Lean In, which is that women run half our companies and countries and men run half our homes. As much as I wish that could happen in four years, I don't think that's a likely time period. But I think it can happen sooner than we think. Part of it is having that aspiration and that goal. I think we too often suffer from the tyranny of low expectations.

Women attribute their success to working hard, luck, and help from other people. Men will attribute that - whatever success they have, that same success - to their own core skills.

The things that hold women back, hold them back from sitting at the boardroom table and they hold women back from speaking at the PTA meeting.

I walk out of this office every day at 5:30 so I'm home for dinner with my kids at 6, and interestingly, I've been doing that since I had kids. I did that when I was at Google, I did that here, and I would say it's not until the last year, two years, that I'm brave enough to talk about it publicly. Now I certainly wouldn't lie, but I wasn't running around giving speeches on it." "...there's no such thing as work-life balance. There's work, and there's life, and there's no balance.

My hope in writing 'Lean In: Women, Work, and the Will to Lead' was to change the conversation from what women can't do to what we can.

Two things that I think matter are gratitude and joy.

I spent most of my career, including my time at McKinsey, never acknowledging that I was a woman. And, you know, fast forward - I'm 43 now - fitting in is not helping us.
