“...I cannot live without brain-work. What else is there to live for? Stand at the window here. Was ever such a dreary, dismal, unprofitable world? See how the yellow fog swirls down the street and drifts across the dun-colored houses. What could be more hopelessly prosaic and material? What is the use of having powers, doctor, when one has no field upon which to exert them? Crime is commonplace, existence is commonplace, and no qualities save those which are commonplace have any function upon earth.”
― Arthur Conan Doyle, The Sign of Four

“And the past held only this wisdom: that love was a damaging mistake, and its accomplice, hope, a treacherous illusion. And whenever those twin poisonous flowers began to sprout in the parched land of that field, Mariam uprooted them. She uprooted them and ditched them before they took hold.”
― Khaled Hosseini, A Thousand Splendid Suns

“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”
― Robert A. Heinlein

“The truly creative mind in any field is no more than this: A human creature born abnormally, inhumanly sensitive. To him... a touch is a blow, a sound is a noise, a misfortune is a tragedy, a joy is an ecstasy, a friend is a lover, a lover is a god, and failure is death. Add to this cruelly delicate organism the overpowering necessity to create, create, create -- so that
without the creating of music or poetry or books or buildings or something of meaning, his very breath is cut off from him. He must create, must pour out creation. By some strange, unknown, inward urgency he is not really alive unless he is creating.”
― Pearl S. Buck
