Leadership is about making others better as a result of your presence and making sure that impact lasts in your absence." (Harvard Business School definition of leadership)

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.

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.

No industry or country can reach its full potential until women reach their full potential. This is especially true of science and technology, where women with a surplus of talent still face a deficit of opportunity.

Women have made tons of progress. But we still have a small percentage of the top jobs in any industry, in any nation in the world. I think that's partly because from a very young age, we encourage our boys to lead and we call our girls bossy.

Over the last 10 years, women have stalled out at the top.

I want my daughter to have the choice not just to succeed, but to be liked for her accomplishments.
