Happiness, defined as a combination of life satisfaction, coping resources, and positive emotions, predicts desirable life outcomes. The broaden-and-build theory suggests that positive emotions help build lasting resources. A study tracked daily emotions of 86 students over a month and found that positive emotions increased resilience and life satisfaction, while negative emotions had minimal effects. Positive emotions mediated the relationship between baseline and final resilience but not life satisfaction. This suggests that in-the-moment positive emotions, not general life satisfaction, link happiness to better outcomes. Resilience growth mediated the relationship between positive emotions and increased life satisfaction, indicating that happy people become more satisfied by developing resources for living well. Positive emotions and ego-resilience are interrelated, with ego-resilience providing benefits in both negative and positive situations. The study tested hypotheses that positive emotions predict increases in ego-resilience, which in turn predicts increased life satisfaction. Negative emotions did not significantly affect the associations among positive emotions, ego-resilience, and life satisfaction. The study used computer-validated diary data to examine the relationships among daily positive emotions, ego-resilience, and life satisfaction. Results supported the broaden-and-build theory, showing that positive emotions lead to increased resilience and life satisfaction. The study found that positive emotions are more predictive of life outcomes than life satisfaction itself. Negative emotions did not reduce the effects of positive emotions, and rising levels of positive emotions were necessary for growth. The findings suggest that positive emotions are a powerful source of growth and change, predicting both individuals' judgments about life and their skills for living well. The study highlights the importance of daily positive emotions in building resources and improving life satisfaction. The research also notes that life satisfaction is more than just the summation of good and bad feelings over time. Positive emotions and ego-resilience are associated with rising life satisfaction, but life satisfaction itself does not contribute to its own positive feedback loop. The study concludes that daily positive emotions can feed a cycle of lifelong growth.Happiness, defined as a combination of life satisfaction, coping resources, and positive emotions, predicts desirable life outcomes.
