Success and likeability are positively correlated for men and negatively for women. When a man is successful, he is liked by both men and women. When a woman is successful, people of both genders like her less.

I think when tragedy occurs, it presents a choice. You can give in to the void, the emptiness that fills your heart, your lungs, constricts your ability to think or even breathe. Or you can try to find meaning. These past thirty days, I have spent many of my moments lost in that void. And I know that many future moments will be consumed by the vast emptiness as well. But when I can, I want to choose life and meaning.

Every woman I know, particularly the senior ones, has been called too aggressive at work. We know in gender blind studies that men are more aggressive in their offices than women. We know that. Yet we're busy telling all the women that they're too aggressive. That's the issue.

Men can comfortably claim credit for what they do as long as they don't veer into arrogance. For women, taking credit comes at a real social and professional cost.

We've ceased making progress at the top in any industry anywhere in the world . In the United States, women have had 14% of the top corporate jobs and 17% of the board seats for 10 years. Ten years of no progress.

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.

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