Saint-Exupéry grasps something most wisdom overlooks: that vision itself—not merely what we choose to look at—changes depending on our emotional state. A parent watching their child's clumsy drawing doesn't see the crooked lines; they see devotion. A stranger sees only pencil mistakes. The difference isn't information available to the eye but the heart's capacity to organize meaning around what matters most. This is why we can stare directly at someone's kindness for years and miss it entirely until we've loved them.
