I bought this book because I wanted to find a way to move on in life. I had a feeling of what Shah himself says - "If you always do what you've always done, you'll always get what you've always got."
The book provides a highly accessible introduction to the techniques of neurolinguistic programming in nicely digestible chunks. It is an eye opener in many ways, especially as it is mindful in telling you that you can't use this to change other people, but you can change yourself so that other people relate to you better.
Whether you want to learn how better to influence people, how to overcome phobias or how to prepare yourself for any situation, this book is an excellent starting point. It may be all you need in itself, and if not, Shah provides a helpful list of further reading and information resources to further your studies.
It warrants a second read or more to make sure you've fully grasped all of what it gives you. I found myself at times so enthused at what I was reading that I didn't really take it in. Next read, pad and pen at the ready and then I can properly learn how to change my filter so that I no longer need to write things down in order to commit them to memory.
