I read too much Heinlein at a formative age, but this quote from Time Enough for Love always struck me: > 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, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. Most things are possible for most people to do if they bother and take an interest in it. Quite often people will just throw up their hands and claim they can't do something, rather than rolling up their sleeves and giving it a go.
