I was supposed to be authoritative, but at the same time had to be likeable, a quality that is a bonus, not a requirement, for men in the same position.

Women have a lot of power in private life. There are many men who would say, 'Hey, women already rule my life.' But with women, more is more. The more there are, the more the world gets used to seeing them. We change the culture. We begin to expand options and lead and manage.

Many differences are rooted in biology and reinforced through culture, so it's important to acknowledge that. Because if you say men and women are the same and if male behaviour is the norm, and women are always expected to act like men, we will never be as good at being men as men are.
