Hope is the most exciting thing there is in life.

Because I'm in an adult world and I'm really working, my age is just a number. It's not really who I am.

I travel the world visiting global health programs as an ambassador for the global health organization, PSI, and sometimes the disconnect I see is truly striking: people can get cold Coca Cola, but far too infrequently malaria drugs; most own mobile phones, but don't have equal access to pre-natal care.

Growing up in the public spotlight and having insecurities like every other girl, I really know what it's like to feel self-conscious.

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 didn't take the decision [to get married] lightly. I ventured into it realistically. But life takes you places you wouldn't have expected. I'm really content with what was in the cards for me.

I'm a spiritual person and a religious person. But for me, it's all a personal thing. I'm not someone who'll say, 'This is what I believe, and you should too!' It's more of an internal, quiet, grounded, fulfilling thing for me.
