The Domino Effect

i want to preface this with the a, the sub title here, because i think this sets the tone for the whole book. The subtitle is the surprisingly simple truth behind extraordinary results. I would say the most important takeaway from the book pens before the first part, in the introduction. A single domino can topple another domino up to 50 % larger. And this is not something that is originated from garry keller, by the way. It's more credit than charles duhi gave the m i t professors who came up with the k routine reward thing.
