I saw Cheaper by the Dozen - the original from 1950 - when I was about 12 years old. It was based on the true story of Lillian and Frank Galbraith, the parents of twelve children, Both were efficiency experts, and much of the movie dealt with how Lillian ran the household like the Swiss run the trains after the death of Frank.
My parents ran a fly-in fishing resort on an island in Ontario’s north woods. My mother, like Lillian, oversaw the cleaning and maintenance of the lodge with precision; each room cleaned from floor to ceiling once a week, each room had a checklist and order of operations.
Those two influences crystalized my fascination with how we get things done.
