Answer to Question 1
Happiness researchers generally share a popular assumption that we each have a happiness set point. The happiness set point concept is based on the well known weight set point idea discussed in the weight loss literature. Think of how a thermostat works on an air conditioner and heater. The thermostat sets the point for the temperature so that when the ambient temperature gets too hot, the air conditioner blows to bring the temperature down to the set point. When it gets too cold, the heater blows to bring the temperature up to the set point.
Answer to Question 2
Today, Carol Ryff's model of psychological well-being (PWB) embodies the eudaimonic concept, but instead of virtues, it substitutes dimensions of positive mental health. In her view a person must exhibit high levels of six dimensions of positive mental health in order to experience the highest levels of well-being. Ryff identified these six dimensions based on her understanding of classic theories of what determines good mental health along with research findings from personality, developmental, and clinical psychology. She named these dimensions self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth.
