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

Let's have an honest conversation about what's going on. A man and a man at a bar looks like mentoring. A man and a woman at a bar looks like dating.

Women are not making it to the top. A hundred and ninety heads of state; nine are women. Of all the people in parliament in the world, thirteen per cent are women. In the corporate sector, women at the top - C-level jobs, board seats - tops out at fifteen, sixteen per cent.

I'm not telling women to be like men. I'm telling us to evaluate what men and women do in the workforce and at home without the gender bias.

What I tell everyone, and I really do for myself is, I have a long-run dream, which is I want to work on stuff that I think matters.

I spent most of my career, including my time at McKinsey, never acknowledging that I was a woman. And, you know, fast forward - I'm 43 now - fitting in is not helping us.

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)
