If you don't believe in yourself nobody else will believe in you.

When I was 10 or 11 people started saying there was something special about my voice. But when I was 15 or 16 is when I really thought my hobby could become my career.

And that's the kind of thing people think, you know, that if you sign up to be a singer-songwriter you know how to deal with people setting up hate websites, or people being obsessed with you and crying when you touch them, but you don't, and you just have to deal with.

I had knockback after knockback before I got anywhere. After I got my first record deal I thought that was it, then Gut Records went into liquidation. I was 20. I had no idea what that meant. I had a few days to get myself out of that contract or my work would be owned by someone else.

However old you are, however much you love life, however happy you are, how healthy you are, it doesn’t matter. Nothing’s guaranteed. And I think it made me want to take that risk to expose myself as me and not as a version of myself. I don’t become Jessie J. I might put a nicer pair of heels on and a cooler outfit, but I’m still that naughty girl who likes a slice of cheesecake on my day off.

I think if I wasn't a singer I'd probably do make-up and beauty and hair and something creative like styling; I really enjoy it.
