I realized that the only way to get into a good college was to be valedictorian or salutatorian. So that was my goal.

Vaccines are a miracle cure. Eight out of 10 children are getting vaccines.

I'm wholehearted about whatever I do.

You can't save kids just with vaccines.

In the developing world, they don't have smartphones yet. They have the older plastic phones, but women are saving money on those, because they don't have access to banks. Having that access to digital money changes everything for her because she actually doesn't have to negotiate with her husband, which she will tell you is very hard in these circumstances, especially when the means are meager. She's expected to have money to pay for the kids' health or to help with the school fees.

In different places you run into myths around vaccination or around family planning. In the United States, one of the myths that existed for a long time, that has been completely debunked, was that autism was linked to a vaccine.

Like in Africa, if somebody doesn't have fuel, they're still going and collecting firewood. If they get an oven, that's a huge difference. You can do things to reduce the inequities by making sure that they can get clean energy, safe energy. To make sure they're not having to collect water every day. That's huge for women in the developing world.
