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.

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

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.

Our culture needs to find a robust image of female success that is first, not male, and second, not a white woman on the phone, holding a crying baby.

Believe in yourself and negotiate for yourself. Own your own success.

I believe we need affordable child care. I believe we need flexibility. I believe we need institutional reform and public policy reform.

We need to start talking about child-rearing in the workplace.
