Women and girls have been my passion for my whole life.

I'm inspired by the resilience of people around the world.

When the Berlin Wall fell and suddenly all those countries had burgeoning democracies, women were still being left out. The big turning point, about ten years ago, was moving from a notion of empowering women to actually looking at where you can make the most difference, and it's in a girl's life.

Change always starts with a girl.

Global is a unifying bond for people. Once they get outside their own heads and their own communities and see themselves in a broader framework, it really changes their sense of what they can get done. It all adds up for us.

Tomorrow is Now... If we act, 2015 can be a year for the history books. It can be the year that we put the world on the path to end extreme poverty; the year we place sustainability at the heart of our future; and the year that we agree that every person should be able to lead a life of dignity and opportunity.
