I was fascinated by a comment made by the singer, Sinead O'Connor in The Times recently. She acknowledged that she had revealed so much of her personal struggles in articles over the years. "I don't do regret," she said. In fact, she believes it is her job as an artist to lay herself bare. "Artists are here to do your madness for you. We're here to say the things you can't say, because you have to go to work and you don't have time to go to the nuthouse."
