Morgan Housel opens with a fact that resets everything: Adam Smith wrote that it was common in 18th-century Scotland to meet a mother who had borne twenty children and had not two alive. Queen Anne of England had 18 children. Not one made it. Today we complain about grocery stores having too many options.
