旅行是一种残酷。它迫使你信任陌生人，失去所有熟悉的家庭和朋友的舒适感。你不断地失去平衡。除了基本的东西：空气、睡眠、梦想、海洋、天空——所有趋向于永恒或我们想象中的永恒的东西，没有什么是属于你的。
"Traveling is a brutality. It forces you to trust strangers and to lose sight of all that familiar comfort of home and friends. You are constantly off balance. Nothing is yours except the essential things: air, sleep, dreams, the sea, the sky - all things tending towards the eternal or what we imagine of it."
