Music is my passion. It's my priority. I love it.

I love music and I guess I have less expectations or pressure to kind of put on myself because the music hasn't been some huge sensation.

I guess I have sort of an atypical relationship with my mom for someone my age, because I think I started so young with the music thing and I had my parents always on the road with me. So at a time when I think I should have been rebelling like in high school, they were actually my best friends.

I always think about the simplest things in a relationship that have frustrated me. It always sort of comes down to communication. Even something as simple as probably the worst thing that could happen is, 'Where do you want to go to dinner?' 'I dunno. Where do you want to go to dinner?' 'I dunno.' That might be the worst thing in the world.

I take advantage of the opportunities that have come my way. I think I've lucked out that I've never been thrust in the spotlight where people wanted to dissect every aspect of my life. I've been given a lot of distance and respect. It's allowed me the best of both worlds. I have the job of my dreams, but I also have the freedom that doesn't always come with it. I feel very lucky in that sense.

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.

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