"A man needs to travel. On his own, not through stories, images, books or TV. He needs to travel for himself, with his own eyes and on his own feet to understand what belongs to him. So that he might someday plant his own trees and value them. He must know cold in order to enjoy heat. And vice-versa. He must experience distance and homelessness in order to feel at home under his own roof.
A man needs to travel to places he does not know, he must lose the arrogance that causes him to see the world as he imagines it rather than simply as it is or as it can be, the arrogance that turns us into professors and doctors of what we have not seen, when we should be pupils who simply go and see."
