For any of us in this room today, let's start out by admitting we're lucky. We don't live in the world our mothers lived in, our grandmothers lived in, where career choices for women were so limited.

We're the only developed country in the world that doesn't have paid maternity leave. Paternity leave is just as important. Paid family medical leave so that you can take care of a parent, a child, a grandparent, whatever you need to do. I think we're shortsighted when we don't invest in our employees as companies, and as an economy, because we invest in them and they invest back in us.

The reason I wrote Lean In is I think people weren't actually noticing that we had stopped making progress. I gave a TED talk and said: "It turns out men still run the world." And the audience gasped as if that was news.

We know when we use the full talents of our population we're more productive. And we know that when people really feel like they can have flexible lives, they're better employees.

Leadership is not bullying and leadership is not aggression. Leadership is the expectation that you can use your voice for good. That you can make the world a better place.

We need to talk more openly about mentorships and sponsorships. Women don't get the mentoring, and particularly the sponsors, they need to succeed as much as men.

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.
