„The average man takes life as a trouble. He is in a chronic state of irritation at the whole performance.
He does not learn to differentiate between troubles and difficulties, usually, until some real trouble bowls him over. He fusses about pin-pricks until a mule kicks him. Then he learns the difference.“
— Herbert N. Casson Canadian journalist and writer 1869 - 1951
