I have answered this at Quora.
Wind, Sand and Stars (French title: Terre des hommes, literally “Land of Men”) by Antoine de Saint-Exupéry.
“When I opened my eyes I saw nothing but the pool of nocturnal sky, for I was lying on my back with out-stretched arms, face to face with that hatchery of stars. Only half awake, still unaware that those depths were sky, having no roof between those depths and me, no branches to screen them, no root to cling to, I was seized with vertigo and felt myself as if flung forth and plunging downward like a diver.”
“I looked about me. Luminous points glowed in the darkness. Cigarettes punctuated the humble meditations of worn old clerks. I heard them talking to one another in murmurs and whispers. They talked about illness, money, shabby domestic cares. And suddenly I had a vision of the face of destiny. Old bureaucrat, my comrade, it is not you who are to blame. No one ever helped you to escape. You, like a termite, built your peace by blocking up with cement every chink and cranny through which the light might pierce. You rolled yourself up into a ball in your genteel security, in routine, in the stifling conventions of provincial life, raising a modest rampart against the winds and the tides and the stars. You have chosen not to be perturbed by great problems, having trouble enough to forget your own fate as a man. You are not the dweller upon an errant planet and do not ask yourself questions to which there are no answers. Nobody grasped you by the shoulder while there was still time. Now the clay of which you were shaped has dried and hardened, and naught in you will ever awaken the sleeping musician, the poet, the astronomer that possibly inhabited you in the beginning.”
