“Yes, of course duct tape works in a near-vacuum. Duct tape works anywhere. Duct tape is magic and should be worshiped.”
― Andy Weir, The Martian

“Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind.”
― Ayn Rand, The Fountainhead

“Be what you would seem to be - or, if you'd like it put more simply - never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.”
― Lewis Carroll

“Listen to what is being preached today. Look at everyone around us. You've wondered why they suffer, why they seek happiness and never find it. If any man stopped and asked himself whether he's ever held a truly personal desire, he'd find the answer. He'd see that all his wishes, his efforts, his dreams, his ambitions are motivated by other men. He's not really struggling even for material wealth, but for the second-hander's delusion - prestige. A stamp of approval, not his own. He can find no joy in the struggle and no joy when he has succeeded. He can't say about a single thing: 'This is what I wanted because I wanted it, not because it made my neighbors gape at me'. Then he wonders why he's unhappy.”
― Ayn Rand, The Fountainhead
