I really fancy downshifting (downsizing); I've thought about it for a few years now, ever since I saw a television programme on it. I have this idea of what it would be like - a smaller house with less housework and maintenance, growing my own vegetables, economising, recycling, less reliance on electrical appliances, less work etc. On the programme I saw, some people made major changes very quickly. Is this the way to go or is it something that is best done gradually?
