"Maturity is a quality of personality made up of a number of elements. It is stick-to-itiveness, the ability to stick to a job, to work on it and to struggle through it until it is finished, or until one has given all one has in the endeavor. It is the quality or capacity of giving more than is asked or required in a given situation. It is this characteristic that enables others to count on one; thus it is reliability. Persistence is an aspect of maturity; persistence to carry out a a goal in the face of difficulties. Endurance enters into the concept of maturity; the endurance of difficulties, unpleasantness, discomfort, frustration, hardship. The ability to size things up, make one's own decisions, is a characteristic of maturity. This implies a considerable amount of independence. A mature person is not dependent unless ill. Maturity includes a determination, a will to succeed and achieve, a will to live. Of course, maturity represents the capacity to cooperate; to work with others; to work in an organization and under authority. The mature person is flexible, can defer to time, persons, circumstances. He can show tolerance. He can be patient, and, above all, he has qualities of adaptability and compromise. Basically, maturity represents a wholesome amalgamation of two things: 1) Dissatisfaction with the status quo, which calls forth aggressive, constructive effort, and 2) Social concern and devotion. Emotional maturity is the morale of the individual."
