I agree wholeheartedly with the rave reviews others have given this book/CD, and I second the notion that the "7 Days" part of the title is quite ambitious. But no one can predict how much reprogramming their own mind will need until the work gets under way. In my first few days of listening and reading, before I noticed any real changes in my outlook or my behaviour, I found myself looking forward to the time I would spend on this. So maybe there were changes already happening that were a bit too subtle for me to recognise them. Within about 3 weeks' time, there was no mistaking that my thought patterns were becoming more positive and now (about 3 months since I first bought the book/CD), it's clear that much of the content has stuck with me and plays itself in my head automatically.
The big message is that you can't just spend 7 days and imagine that your life is "fixed." Buy the book and CD, use it steadily for a week, then come back to it from time to time to make sure you don't take a backward slide into old ways of thinking.
The single most important thing that has stuck with me from this CD is that whatever occupies your attention most is what you will create for yourself. So you are the only one who can decide what that will be, but Paul's book and CD can certainly help make it positive and constructive.
If you find you get tired of listening to the same CD over and over (which did happen to me after about 10 days), try alternating this one with Glenn Harrold's positive thinking CD, which is a bit more relaxing. (I like Paul in the morning and Glenn at night. ;)
So off you go to change your life. Who else is going to do it?
