"It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy."
Explanation
Do what you do best, and buy the rest. A smart family does not try to bake every loaf, sew every shirt, and fix every gadget if a neighbor can do it better and cheaper. Time and talent are scarce; trade turns them into more.
This home truth scales up: communities and nations grow richer when people specialize, exchange freely, and let prices guide choices. We all win when we do not try to make everything ourselves.
