"I wish I were as enthusiastic as you." said the young man. Or should I say "said the young ignorant man." Ignorance is not a bad thing, because with just a little information and a little bit of effort, it can be overcome. Enthusiasm is not an accidental gift of the Gods, it is a choice, it is an obtainable attribute that can be strengthened through exercise and discipline, like any other attribute. Make enthusiasm a deliberate part of your personality... start by knowing what it means.

enthusiasm n.
1. Great excitement for or interest in a subject or cause.
2. A source or cause of great excitement or interest.
3. Archaic. a.Ecstasy arising from supposed possession by a god. b.Religious fanaticism. [Late Latin enth siasmus, from Greek enthousiasmos, from enthousiazein, to be inspired by a god, from entheos, possessed : en-, in; see en-2 + theos, god; see dh s- in Indo-European Roots.]

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 enthusiasm one positive and one negative both 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
