“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
There was a time when jacks-of-all-trades were considered invaluable. They could just as easily chop firewood and pitch a tent as they could do their own taxes or write a letter to a senator. They made life richer and more rewarding, for both themselves and others.
