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
and die gallantly.
Specialization is for insects.
Robert A. Heinlein
