“To spare oneself from grief at all cost can be achieved only at the price of total detachment, which excludes the ability to experience happiness.”
― Erich Fromm, Man for Himself: An Inquiry Into the Psychology of Ethics

“The faculty to think objectively is reason; the emotional attitude behind reason is that of humility. To be objective, to use one's reason, is possible only if one has achieved an attitude of humility, if one has emerged from the dreams of omniscience and omnipotence which one has as a child. Love, being dependent on the relative absence of narcissism, requires the developement of humility, objectivity and reason.

I must try to see the difference between my picture of a person and his behavior, as it is narcissistically distorted, and the person's reality as it exists regardless of my interests, needs and fears.”
― Erich Fromm, The Art of Loving

“Giving is the highest expression of potency. In the very act of giving, I experience my strength, my wealth, my power. This experience of heightened vitality and potency fills me with joy. I experience myself as overflowing, spending, alive, hence as joyous. Giving is more joyous than receiving, not because it is a deprivation, but because in the act of giving lies the expression of my aliveness.”
― Erich Fromm, The Art of Loving

“The main condition for the achievement of love is the overcoming of one's narcissism. The narcissistic orientation is one in which one experiences as real only that which exists within oneself, while the phenomena in the outside world have no reality in themselves, but are experienced only from the viewpoint of their being useful or dangerous to one. The opposite pole to narcissism is objectivity; it is the faculty to see other people and things as they are, objectively, and to be able to separate this objective picture from a picture which is formed by one's desires and fears.”
― Erich Fromm, The Art of Loving
