Maturity

"Maturity is first the shedding of what you are not, and then the balancing of what you are in relation to the human being you love, and allowing the selves of that person which are not related to you to exist independently, outside of the relationship."

Anaïs Nin in Diary of Anaïs Nin Volume 5 1947-1955: Vol. 5
