Anais Nin: We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.

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.”

Henri Bergson: To exist is to change, to change is to mature, to mature is to go on creating oneself endlessly.

Mark Twain – attributed in error: When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much the old man had learned in seven years.

Mary Beth Danielson: If growing up is the process of creating ideas and dreams about what life should be, then maturity is letting go again.
