But the upside of painful knowledge is so much greater than the downside of blissful ignorance.

Leaders should strive for authenticity over perfection.

We're focused on doing one thing incredibly well. If you look at other companies, all of these companies are doing a lot of different things but we're still, as we grow, doing exactly one thing.

Today, despite all of the gains we have made, neither men nor women have real choice. Until women have supportive employers and colleagues as well as partners who share family responsibilities, they don't have real choice. And until men are fully respected for contributing inside the home, they don't have real choice either.

Framing the issue of work-life balance - as if the two were dramatically opposed - practically ensures work will lose out. Who would ever choose work over life?

The time is long overdue to encourage more women to dream the possible dream.

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