“All of us,’ he said, ‘have hopes of being poet, artist, discoverer, philosopher, scientist; of possessing the attributes of all these simultaneously. Few are permitted to achieve any of them in daily life. But in travel we attain them all. Then we have our day of glory, when all our dreams come true, when we can be anything we like, as long as we like, and, when we are tired of it, pull up stakes and move on. Travel — the solitude of the mountains, the emptiness of the desert, the delicacy of the minaret; eternal change, limitless contrast, unending variety.’
