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 write a lot on airplanes actually because it's completely isolating; there's no one to talk to, there's nothing to do.

I'm really kind of boring - I'd rather go to bed early and get up early because I really value my time off, my time away from work.

I'm slightly controlling. I'm an Aries and I like things to have an order. I get slightly disturbed and I get slightly distressed and flustered if things go awry.

We live in a cynical world now, and it's nice to be part of entertainment that is hopeful and heartfelt and wears its heart on its sleeve, but isn't saccharine. It's real. It's grounded.

I love the idea of getting up early on Sundays and walking to the market to pick up fresh fruits and vegetables. It's a good way to start my day, and it makes me feel like I've accomplished something before other people are even awake.

Growing up in the public eye was really tough. When you're 14 and your body is changing, your life is changing, and people are watching every step you make, it's really hard to deal with. But I was pretty lucky, people didn't watch me that closely.
