there is a methodology so powerful, so straightforward, so accessible and low cost that it has attained an almost mystical quality amongst its followers and practitioners: the list. Take an A4 sheet of paper: lined, squared or plain. Add a pencil: propelling is perfect. And write. Whatever your challenge or concern, the list will solve it: Christmas shopping, start-up plans, characters in novel or fitness regime. Focusing, solving and at times downright cathartic. 100% organic and public domain. You need a list. Or two.
