He describes habits, but also how they arise and how they can be changed. He weaves in an inimitable way different, sometimes very unexpected examples of habits with each other. The greatest strength of the book is really masterful narrative of different stories to illustrate habits. This is so exciting and interesting that the book reads almost like a thriller. The examples come from the football, of Alcoholics Anonymous and from the American Bürgerrechtsbwegeung, just to name a few.
Our life is determined by habits - without us noticing it. But habits can be changed. A first step is to see through. These can stimulate this book. But it is also clearly said that habits are not as simple as they appear, and there is no standard recipe to change habits.
So you should not have any instructions from this book "How to change" expected. But we should definitely expect masterful entertainment.
