I think I was always an old soul, even as a teenager.

I only say this because a lot of people seem to think that if you're a musician you want to be a celebrity. But most musicians in the world aren't celebrities, and pretty much everything about the concept of 'celebrity' is a complete load of bollocks anyhow.

Obviously, it was a big life change for me and quite a shock to suddenly have these songs I'd written in my bedroom as a far-too-intense teenager all over the airwaves and see my face on buses, especially in a small country like New Zealand, but at the same time it was such a thrill and an honour knowing that my music was reaching people.

I recognise my responsibility, and it's funny when I read people who say they never asked to be a role model, and I understand that, but as soon as you have influence over people, you have a responsibility with what you do with that influence.

I think I was always an old soul, even as a teenager.

At sixteen I was like: "I need to get an album out now!" - even though I was only sixteen. I was always in a little bit of a rush to be an adult.

I've always recognised that I have influence, whether I like it or not, and that I can use it to do something good.
