Explain the three key predictors of happiness.

Happiness is influenced primarily by three factors: social relationships, employment
status, and physical/mental health. Social relationships refer to close friends, marriage
partners, and simply having an active social life, all of which probably help serve to
reduce the self-focus that can impede coping with stress. Employment status does not
refer to income, but simply to being employed. People who are out of work are not as
happy as those who do work, and salary seems to make little difference. Finally, health
seems to have a large impact on well-being. Being healthy, in both the physical and
mental senses, has a positive influence on one's personal happiness.
