In 2009, I traveled to South Sudan with my organization PSI. While there, I visited a local school and met with a group of children who had formed a water club. The group learned about how to treat their drinking water and use proper hygiene practices, such as washing their hands before eating or after going to the bathroom.

I've gone skydiving twice. I was terrified about doing it, but I wanted to overcome that. The first time, I did it with my parents and I remember that they had already both jumped out, and suddenly it was my turn. And I thought, 'Well, I don't want to be an orphan,' so I guess I have no choice, and I jumped out of the plane.

My mom has never been a big meddler and isn't like extremely opinionated or at least just doesn't voice it to me. She's sort of let me come into my own by myself and I think that's just a testament to what my parents did in terms of raising us.
