And when I perform on my own tour, I have to talk myself into going out on that stage every single night.

I like how my body feels when I'm in shape; I love how it feels after I work out each day. Fitting in the clothes I like to wear comfortably and living a healthy lifestyle is important to me.

When I turned 19 I kinda realized that I needed to write my own songs instead of singing songs written by other people.

Bob Marley is a huge influence. I love reggae music, but I also love the purpose of the songs he writes and the style of the music - it takes your worries away and makes you feel good, and I think that's what music is about.

I love 'Breathe' with Taylor (Swift) but I've been performing 'Lucky' with Jason (MRaz) all over the world in the past year so I'm glad that's what won.

What's really cool is to be able to write music and have people around the world [who are] able to relate to it. They tell you that [your] song helped them get through a divorce or they got married to that song. It makes me want to keep doing that for [myself] and for people.
