A man needs to travel. By his means, not by stories, images, books or TV. By his own, with his eyes and feet, to understand what is his. For some day planting his own trees and giving them some value. To know the cold for enjoying the heat. To feel the distance and lack of shelter for being well under his own roof. A man needs to travel to places he doesn't know for breaking this arrogance that causes us to see the world as we imagine it, and not simply as it is or may be. That makes us teachers and doctors of what we have never seen, when we should just be learners, and simply go see it.
