In this book, the human mind is likened to a factory, where its raw materials are sounds and images that enter through the ears, eyes, and other senses in the form of speech, behavior, and creations from the surrounding environment. The final product of this factory is speech, produced through the mouth, and behavior, manifested by the human. The goal and final product of this factory is the production of value, which is defined as a good feeling (which may come in the form of money, power, fame, character, peace, security, love, etc.).All the efforts of humans around the world, from a newborn in the East of Asia to an elderly person in America, from the beginning of creation to forever, are driven by two causes: 1- To create a good feeling. 2- To avoid feeling bad.In this book, using various engineering sciences, the issues related to controlling the quality of inputs to the mind's factory, the methods of production within the mind, and the quality of the final product of the mind's factory are evaluated and analyzed. Psychological issues and other success and self-help concepts discussed in other books are presented from the perspective of this book in simple language for general use.
