"A human being should be able to change a diaper, plan an invasion,
butcher a hog, steer a schooner, 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, and die gallantly. Specialization is for insects."
This was said by Robert Heinlein in Time Enough for Love, and should be remembered
