Shelter, food, water, warmth — all these are primal needs. I think there's an inbuilt satisfaction that we feel when we satisfy one of these needs with mind and body. There is little else that produces that feeling. So, though we are busy, though our time may be more costly than hiring an expert, we build buildings, we raise meat and vegetables, we split wood, we light fires, and we feel the satisfaction that our earliest ancestors must have felt when they did the same.

It is good and right that we do these things.
