How did Freud see primary Narcissism and why?

Freud categorized primary Narcissism as "loving oneself". We all have impulses to nourish ourselves and to protect ourselves from danger; these impulses are bound up with our desires, and we can't neatly seperate our sexual desires (directed at humans) from our inwardly directed desire to care for ourselves. Freud calls the basic, sexually charged desire directed at the self "primary" or "normal" narcissism. He contrasts primary narcissism with "secondary narcissism" which arises in pathological states such as schizophrenia in which the persons libido withdraws from objects in the world and produces megalomania. Secondary narcissism of the mentally ill is a magnified extreme manifestation of primary narcissism which exists in all individuals.
