Enthusiasm

"Every memorable act in the history of the world is a triumph of enthusiasm. Nothing great was ever achieved without it because it gives any challenge or any occupation, no matter how frightening or difficult, a new meaning. Without enthusiasm you are doomed to a life of mediocrity but with it you can accomplish miracles." -- Og Mandino, 1923-1996, Author and Speaker

Word History: “Nothing great was ever achieved without enthusiasm,” said the very quotable Ralph Waldo Emerson, who also said, “Everywhere the history of religion betrays a tendency to enthusiasm.” These two uses of the word enthusiasmone positive and one negativeboth derive from its source in Greek. Enthusiasm first appeared in English in 1603 with the meaning “possession by a god.” The source of the word is the Greek enthousiasmos, which ultimately comes from the adjective entheos, “having the god within,” formed from en, “in, within,” and theos, “god.” Over time the meaning of enthusiasm became extended to “rapturous inspiration like that caused by a god” to “an overly confident or delusory belief that one is inspired by God,” to “ill-regulated religious fervor, religious extremism,” and eventually to the familiar sense “craze, excitement, strong liking for something.” Now one can have an enthusiasm for almost anything, from water skiing to fast food, without religion entering into it at all
