"People need to travel. By ourselves, not only through stories, pictures, books or TV. We need to travel for our own sake, to see the world with our own eyes and to walk on it with our own feet, in order to understand what is ours. We need to do that so we can plant our own trees and avoid taking them for granted. We need to experiment cold days in order to learn how to enjoy the warm days. And the opposite. We need to feel lonely and far so we can appreciate our own home. People need to travel to places that they don’t know in order to get rid of this arrogance that makes us see the world as we imagine it, and not only as it really is or can be. We need to travel so we can stop being professors or specialists of what we did NOT see, when we should have been students, and simply go and see it."
