As I like to say, “Consistency is the most overrate virtue.” But two much smart men have said it better.
The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.
-F. Scott Fitzgerald, “The Crack-Up” (1936)
A foolish consistency is the hobgoblin of little minds.
-Ralph Waldo Emerson, “Self-Reliance”
