My own foundation concentrates on women's economic empowerment on the basis that if women have their own money and are able to support themselves, they can make choices about what happens to them in their lives, about whether they have education, whether they get married, and what happens to their children.

I have never been ashamed of calling myself a feminist, and I believe passionately in women's rights.

Many of the big decisions over progression, promotion and future career trajectory are taken when people are in their late twenties and thirties, putting women at a huge disadvantage because this is the very time they are most likely to be having a break to have children.

I don't know anybody who thinks they have it all... I count myself extremely lucky to have a fantastic family and the career I always wanted.

The only distribution of wealth which is the product of labor, which will be honest, will come through a more equal distribution of the productive capacity of men.

I recall an 18-year-old girl named Rachel in Zambia who was given a grant to start a business of her choosing. She decided to breed goats so she could sell the meat and the milk, and donate the kids to orphan children. She herself was an orphan, stepping into young adulthood with no resources, and it was her first opportunity to earn her own money.

I love my wife. She had money when I didn't.

Whatever you do needs to be sustainable over time, and taking the money in the short term and taking it in a bubble - like buying an Internet stock in 2000 - may not be sustainable.
