I WAS A REBEL WITH ORANGE HAIR AT 13

"Being a mixed-race kid was difficull."

"I looked absolutely dreadful... and was known as 'the bad girl' in school."
"I was really jealous of the leaders and tough older girls... and became really angry when I was 13 because you're insecure about how you look and where you fit in."

"Since I started writing songs at 13, I have worked like dog."

"When my older f,iends left school I was forced to face up to the other kids my gang had rejected."

"People can do anything that's physically possible if they have talent and determination. "

"It's not that I want to be a role model, because I'm not perfect."

"I feel like I can make someone feel more acceptable and will always connect with teenage outsiders."
