Book excerpt: Judith O'Reilly embarks on a year long social experiment in the witty 'A Year of Doing Good'. Fed up of New Year's resolutions involving diets and exercise abandoned on January 2nd, Judith is attempting to be good. For one whole year. She embarked on a mission to do one good deed every day. Some called it a social experiment. At times she called it madness. Juggling family, friends and a variety of neighbours in the small Northumberland village she calls home, she recounts the ups, downs, moments of doubt and sheer bloody hard work of doing good.
