We call ourselves a liberal nation, whereas, as a matter of fact, we are one of the most conservative nations in the world. If you want to make enemies, try to change something. You know why it is. To do things to-day exactly the way you did them yesterday saves thinking. It does not cost you anything. You have acquired the habit; you know the routine; you do not have to plan anything, and it frightens you with a hint of exertion to learn that you will have to do it a different way to-morrow.

Woodrow Wilson (1856-1924) US President (1913-20), educator, political scientist

“The Democracy of Business,” speech, Salesmanship Congress, Detroit (1916-07-10)
