Life Passion noun.
A strong enthusiasm for the condition, quality, or fact of being a living organism, and all that that entails. Not merely the inclination to follow through with routine each day, but an ongoing awareness, curiosity and revelling of the beauty and/or potential in each aspect of each day. This is manifest in a theoretical burning ember in one's essence. Varying from a dim light to a blazing flame, this ember is vanquished only when one's life has ended. Does not seem to be present in every "living" human being.
