We need women at all levels, including the top, to change the dynamic, reshape the conversation, to make sure women's voices are heard and heeded, not overlooked and ignored.

My hope in writing 'Lean In: Women, Work, and the Will to Lead' was to change the conversation from what women can't do to what we can.

I really think we need more women to lean into their careers and to be really dedicated to staying in the work force.

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.

Until women are as ambitious as men, they're not gong to achieve as much as men.

If more women are in leadership roles, we'll stop assuming they shouldn't be.
