It doesn't have to be seven consecutive days!
A friend of mine bought this book and it was very powerful. He practised the techniques as described, rather than thinking about practising them, and big changes happened.
This is the sort of thing that can happen with well applied NLP,
providing you check your environment - that is that the people around
you are ready to come with you when you move, or you only move as fast
as they are able to accept. How far do you want to go, and where are
you starting from?
