Christopher McCandless: The sea's only gifts are harsh blows, and occasionally the chance to feel strong. Now I don't know much about the sea, but I do know that that's the way it is here. And I also know how important it is in life not necessarily to be strong but to feel strong. To measure yourself at least once. To find yourself at least once in the most ancient of human conditions. Facing the blind deaf stone alone, with nothing to help you but your hands and your own head.
