By Daniel Pink
Pink is an expert in human motivation, and goes in-depth about what drives people to improve, as well as the effectiveness and ineffectiveness of extrinsic rewards. Essentially, it comes down to three ideas that follow: the autonomy of self-directing one's life, the mastery of a certain skill which matters to them, and the purpose to have them live a rich and meaningful life. One can reward themselves as much as they want extrinsically by means of products, but ultimately that product will be old and need to be replaced. Like in Ultralearning, having students set their own goals is a huge factor in giving them their own sense of autonomy, and in doing so increase productivity drastically. This directly translates into their personal lives directly, and gives them more of a sense of purpose.
