On Enthusiasm
Arnold J. Toynbee, world historian and author of A Study of History, the longest written work in the English language:
“Apathy can be overcome by enthusiasm, and enthusiasm can only be aroused by two things: first, an ideal, which takes the imagination by storm, and second, a definite intelligible plan for carrying that ideal into practice.”
Hat tip to Alexander the “Chief Happiness Officer” at Happy at Work for the quote.
