I’ve never read Robert Heinlein but when I was a teenager I was swept away by a quotation attributed to one of his characters, Lazarus Long, in Time Enough for Love —

“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.”
