As a country and as a world, we are not comfortable with women in leadership roles. We call little girls bossy.

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.

After my husband, Dave, died, I called my friend Adam, a psychologist who studies how people find meaning in our lives, and I asked him what, if anything, I could do to help myself and my kids get through this. We started talking about resilience, then reading about it, then talking to other people who had gotten through grief and other huge challenges. In time, those conversations and that research helped me heal.

There's a lot that needs to be fixed in dating for men and women in the U.S. - there's a lot of pressure on women to do things they may not want to do. And if you start out unequal, you are not going to end up with equality.

If you do please everyone, you are not making enough progress.

Excel and you will get a mentor.

When you're more valuable, the people around you will do more to make it work.
