It’s book on martial arts and the Dao (way) of the warrior, but Musashi draws upon the four classical Daos that were prevalent in Japanese society, the way of the peasant, the way of the merchant, the way of the warrior, and the way of the artisan. As someone studying engineering management in the context of a technical skill and discipline, this line was enlightening. How do you manage a team or an organization? You first start with managing one person – yourself. Manage yourself and you can manage others.
