The title of this book might suggest changing careers or relationships, or your circumstances. But I think the main message is that for the world to change, you have to change. Life has an uncanny way of showing us where we are going wrong, but, perhaps, we don't always recognise this. Our lives reflect back to us what our beliefs say the way things should be.
As Andrew says, the universe has no favourites where success is concerned; what we reap, we sow. In the chapter regarding Attachment, the more concerned about the outcome we are, the less likely it is to achieve.
The chapter on Change was particularly instructive; how many times have we hoped for a situation, partner, job etc to improve, when we should ask for a change in ourselves?
The book is easy to read and dip into. It is similar to Being Happy!: A Handbook to Greater Confidence and Security
, by the same author. The cartoons don't quite seem to hit the mark in this book, though.
