Robert Greene, in the excellent book Mastery, argues that to master the mind, master the hands:
“Finally, we live in a culture that generally values intellect and reasoning with words. We tend to think of working with the hands, of building something physical, as degraded skills for those who are less intelligent. This is an extremely counterproductive cultural value. The human brain evolved in intimate conjunction with the hand. Many of our earliest survival skills depended on elaborate hand-eye coordination. To this day, a large portion of our brain is devoted to this relationship. When we work with our hands and build something, we learn how to sequence our actions and how to organize our thoughts. In taking anything apart in order to fix it, we learn problem-solving skills that have wider applications. Even if it is only as a side activity, you should find a way to work with your hands, or to learn more about the inner workings of the machines and pieces of technology around you.” #books
