Good self-help books have two important qualities. Firstly, they should explain things in a simple, clear and engaging way. They should help us to understand ourselves in a whole new light. This can be a very reassuring experience. Hopefully we will find out that we are not ‘crazy’ and that that other ‘normal’ people also experience these problems and also that they can get better. Secondly, the best self-help books provide a down-to-earth and practical plan of action; a route-map to pick our way out of the particular life difficulties we are facing.
