This book is very light and entertaining. However, the story is an ill-concocted version of the Seven Habits of highly effective people by Dr. Stephen Covy, which is, by the way, the book you should REALLY get.
Contrary to this lame copied version of poor story-telling, the Seven Habits is a very deep and moving book. It has substance and depth and if you are prepared to listen, it will change you life.
Ok, back to this book... the book is alright I guess, if not for the very annoying fact that the story is completely based in the Seven Habits, it shows a lighter version of the habits that may be entertaining, or otherwise a good way to get into the habits. Who knows, it may lead you to the other book, which is good.
If you prefer substance over "lightness", don't get this book. Furthermore, as another reviewer puts it, is poorly writen.
I'm only giving two stars over one, because the habits in which it is based are really something to look into...
