The proof of the pudding is in the eating.
Apart from gaining a great deal of useful insight from this book myself, I have recommended it to several Clients (I work as a Hypnotherapist and Life Coach)who have suffered with depression, anxiety and plain old procrastination.
They have each found much food for thought here, and managed to make sense of much of what was troubling them. I would like to claim this is all down to me of course - but the simple truth is that Geoff Thompson has a way of taking complex ideas and making them accessible to all.
If you want to spend 20 years wading through hundreds of great works, by some of the intellectual giants, to find meaning to your life (and there is nothing wrong with that!) do so. If you want to learn from somebody who has walked that path, and has the ability to distil it all down to plain English - read Geoff Thompson. You will end up in the same place eventually, but the journey may be considrably shorter and quicker if you walk in his footsteps!
