Erich Fromm said this quote

Love is a decision, it is a judgment, it is a promise. If love were only a feeling, there would be no basis for the promise to love each other forever. A feeling comes and it may go. How can I judge that it will stay forever, when my act does not involve judgment and decision.

~ Erich Fromm

Infantile love follows the principle: I love because I am loved. Mature love follows the principle: I am loved because I love. Immature love says: I love you because I need you. Mature love says: I need you because I love you.

~ Erich Fromm

Modern man has transformed himself into a commodity; he experiences his life energy as an investment with which he should make the highest profit, considering his position and the situation on the personality market. He is alienated from himself, from his fellow men and from nature. His main aim is profitable exchange of his skills, knowledge, and of himself, his personality package with others who are equally intent on a fair and profitable exchange. Life has no goal except the one to move, no principle except the one of fair exchange, no satisfaction except the one to consume.p97.

~ Erich Fromm

If the meaning of life has become doubtful, if one's relations to others and to oneself do not offer security, then fame is one means to silence one's doubts. It has a function to be compared with that of the Egyptian pyramids or the Christian faith in immortality: it elevates one's individual life from its limitations and instability to the plane of indestructability; if one's name is known to one's contemporaries and if one can hope that it will last for centuries, then one's life has meaning and significance by this very reflection of it in the judgments of others.
