There are certain things that are fundamental to human fulfillment. The essence of these needs is captured in the phrase 'to live, to love, to learn, to leave a legacy'. The need to live is our physical need for such things as food, clothing, shelter, economical well-being, health. The need to love is our social need to relate to other people, to belong, to love and to be loved. The need to learn is our mental need to develop and to grow. And the need to leave a legacy is our spiritual need to have a sense of meaning, purpose, personal congruence, and contribution Stephen R. Covey
