My Bandolino (son) wants to get a small tattoo at the nape of his neck in the shape of an infinity symbol that says, "Fear is a Choice" [quote from Will Smith in the movie After Earth -- who knew the fresh prince would get so eloquent. :-)]
"Enthusiasm" is one of my favorite words. I define it as energetic passion with a smile. It is the word I wake up to in my head. I was thrilled and moved to find it has its root in the Greek language, literally it means "the God (entheo) inside (iasm)".
