We also look at farming. Are we making sure that we're getting the latest seeds out to women so they can get a bigger yield off of their farms? A new type of seed that gets out to a man, let's say, that's drought resistant - because, of course, the rains are changing in Africa with climate change - if you don't put it in the hands of a woman, she won't necessarily get it. We look at breaking down all those barriers.

We set out what's going to be our work time versus our foundation time versus family time, and we'll reassess that... sometimes every week.

Having children made us look differently at all these things that we take for granted, like taking your child to get a vaccine against measles or polio.

Our economies are built on the backs of all this unpaid labor that women do.

Kids are falling through the cracks and nobody notices it. That to me is what's wrong with the school system.

With economic opportunity, sometimes it's making sure that if they're not in a place where they can have good jobs, that when they have economic opportunity, they have digital tools to use.

We [with Bill Gates] started to make decisions about what we'd invest in. Then I actually started traveling for the foundation. I've probably been to India now eight times at least and Africa numerous times.
