I had this temp receptionist job in New York and I kind of hated it and in the morning I would come out of the subway and just walk along the New York streets with all these people around me and kind of sing to myself. Like 'She's gonna make it!'
There's also a sense of freedom. I was so obsessed by this problem that I was thinking about if all the time - when I woke up in the morning when I went to sleep at night and that went on for eight years.
