This book, easy to read, is devoted to the motivation to work and already has a well-known thesis, namely that there are two types of motivation. On one hand, extrinsic motivation built on rewards and benefits granted by the company and, secondly, the intrinsic motivation and self-motivation, built on the mobilization of resources of the personality. In the experiment, external motivation is not very effective unless lorqu'elle respect of mechanical and repetitive tasks. Internal motivation, much more effective, is built on the need for autonomy, the ability to get involved and the need for finality (the work to be done). The author supports his thesis on the pyramid of human needs proposed by Maslow in 1943 in his famous book "Theory of human motivation" This book presents an extensive bibliography which curiously forget the most important book on this topic: "Motivation to Work" by Herzberg in 1959, including work which demonstrates that the management does not motivate and can only remove factors demotivation. Daniel Pink's book concludes with a toolkit that brings together a collection of commonplaces, without much interest. The main merit of this book that, contrary to what is in his preface nothing innovative is that it reminds managers of the truths they should know, but that, in general, they too often ignore.
