The greatest power you could have in life would come neither from limitless resources nor even consummate skill in strategy. It would come from clear knowledge of those around you—the ability to read people like a book. Given that knowledge, you could distinguish friend from foe, smoking out snakes in the grass. You could anticipate your enemies’ malice, pierce their strategies, and take defensive action. Their transparency would reveal to you the emotions they could least control. Armed with that knowledge, you could make them tumble into traps and destroy them.
