Trying to do it all and expecting that it all can be done exactly right is a recipe for disappointment. Perfection is the enemy.

I feel really grateful to the people who encouraged me and helped me develop. Nobody can succeed on their own.

Facebook is great for women and men. We are enormously flexible. We care a lot about great opportunities for women, we push ourselves to make things as flexible as possible.

We can each define ambition and progress for ourselves. The goal is to work toward a world where expectations are not set by the stereotypes that hold us back, but by our personal passion, talents and interests.

It's more pressure on women to - if they marry or partner with someone, to partner with the right person. Because you cannot have a full career and a full life at home with your children if you are also doing all of the housework and child care.

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

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.
