Firstly, I sincerely believe that Jack Black's Mindstore method works. Since re-reading his books and attending his courses, I have absolutely no doubt of this. This book was my introduction to Mindstore and is, together with his other book, something to which I refer on a regular basis. I cannot recommend it highly enough to anyone who wants to change their way of thinking and their life for the better.
Secondly, there's no doubt that there is material in this book which overlaps with Jack's other book. If you're looking for an introduction to the Mindstore method, either this book or the other one, will enable you to take your first steps. I've found both titles to be invaluable to me at different times, however.. Ultimately, I believe that complete responsibility for achieving personal success DOES lie with the individual, and, this is also a fundamental core value of the Mindstore system. You CAN do anything that you truly desire, but you must believe you can before you have any success..
YOU CAN CHANGE YOURSELF, YOUR CIRCUMSTANCES AND YOU CAN CHANGE THE WORLD! THIS BOOK WILL SHOW YOU HOW, IF ONLY YOU GIVE IT A CHANCE AND PRACTICE IT'S VALUES.
In the words of its author - FANTASTIC!
