I'm a serious optimist. I come from a country where you have little to be hopeful for, and so you have to always be an optimist.

Today, this young woman is me, a Nobel laureate. I'm now on a journey to fulfill the wish, in my tiny capacity, of little African girls - the wish of being educated. We set up a foundation. We're giving full four-year scholarships to girls from villages that we see with potential.

We go into rural communities and all we do, like has been done in this room, is create the space. When these girls sit, you unlock intelligence, you unlock passion, you unlock commitment, you unlock focus, you unlock great leaders.

When women gather, great things will happen.

Leadership is standing with your people. People say you have to live to fight another day, but sometimes you have to show you are a true leader.
