Welcome, Zooey, to my life. While more young people between the age of 25 and 34 are taking out debt relief orders for insolvency than any other age group, I'm that irritating smug girl who has paid off all my debts; who, like Zooey, has several credit cards but with a zero balance on each of them; who starts every month by taking all my rent, money for bills, £150 for a frivolous holiday fund, £300 to pack away into a savings account (for that pathetic hope of a future house) out of my current account before spending anything.
