Make sure you continue to trust what you know now about yourself and stay true to what you believe in

The biggest killers of children around the world are two things: diarrhea and pneumonia. When you think about it, in the United States, kids don't die of diarrhea anymore, but it's a huge problem in the developing world.

Despite the debunking, you have a small group in the last five years that hasn't wanted to vaccinate their children, for instance, for measles. Then, all of sudden, we got an outbreak of measles and kids were starting to die from measles.

Poverty disproportionately affects women around the world.

In the developing world, it's about time that women are on the agenda. For instance, 80 percent of small-subsistence farmers in sub-Saharan Africa are women, and yet all the programs in the past were predominantly focused on men.

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.

It's really one of my all-time favorite things to do. To go out and really see the kids and visit the moms who are in these programs because I think I really get to see what happens on the ground and connect with them about what changes are that happen in their lives because of some of the giving that we're able to do.
