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.

– from Robert A. Heinlein

Refactoring … to what I want yet to do.

  • Design and build a house that works well.
  • Practical knowledge of firearms.
  • Learn to hunt, and butcher the animal, after.
  • Learn to fly an airplane.
  • Design and build an airplane.

In roughly the above order.
