I love it when people say things to me in public and want to meet me, because I want to meet them! Early on, my manager told me, 'If you want to sell 500,000 records, then go out there and meet 500,000 people.'

It's one of the craziest feelings to be on stage and know that you were sitting on your bedroom floor when that song came to be and now there's an arena full of people singing it.

There's room for role models who make mistakes.

I'm not concerned with people seeing me in a certain way. Some people see me as a kid, some people see me as an adult. But I'm seriously not going to complain how anybody sees me, as long as they see me.

Just keep doing 'you', and being who you are and doing what feels natural to you.

For a female to write about her feelings, and then be portrayed as some clingy, insane, desperate girlfriend in need of making you marry her and have kids with her, I think that's taking something that potentially should be celebrated - a woman writing about her feelings in a confessional way - that's taking it and turning it and twisting it into something that is frankly a little sexist.

I suffer from girlnextdooritis where the guy is friends with you and that's it.
