Dan Baker, in his interesting and I think helpful book, What Happy People Know, reminds me of the New Testament, as well as Kubler-Ross, when he writes:
In the ultimate analysis, human beings have only two essential, primal feelings: fear and love. Fear impels us to survive, and love enables us to thrive. This complimentary pair of feelings has been the driving force of human history.The pic is taken from Mark Hemmings' New York City Photographs collection.
