When I sing for myself, I probably sing for anyone who has any kind of hurt, any kind of bad feelings, good feelings, ups and downs, highs and lows, that kind of thing.
I don't remember deciding to become a writer. You decide to become a dentist or a postman. For me, writing is like being gay. You finally admit that this is who you are, you come out and hope that no one runs away.
I never lose that terror of 'this is my last job, I'll never work again.' You can never relax and rely on whatever reputation you've built.
