Once I´ll reach x (…put in one of your personal or professional goals…) I´ll be happy. This is a popular equation many people believe in. It´s promoted by a lot of self-help books as well.
And it´s wrong – or at least incomplete.
One of the central tenets in Positive Psychology is that happiness (positive emotions) actually lead to success. Researchers Julia K. Boehm and Sonja Lyubomirsky gathered the extant scientific evidence supporting this hypothesis for an influential review article in 2008. Ten years later they revisited this article and integrated new findings that corrobate their initial stance: Does Happiness Promote Career Success? Revisiting the Evidence. Here´s an excerpt from the discussion section:
First, the cross-sectional literature supports a correlational link between happiness and various success-related outcomes. Happiness is positively associated with job autonomy, job satisfaction, job performance, prosocial behavior, social support, popularity, and income. Happy people also receive more positive peer and supervisor evaluations […].
Second, […] longitudinal research suggests that people who are happy at an initial time point are more likely to find employment, be satisfied with their jobs, acquire higher status, perform well, be productive, receive social support, be evaluated positively, engage in fewer withdrawal behaviors, and obtain higher income at a subsequent time point.
Finally, […] experimental research demonstrates that when people are randomly assigned to experience positive emotions, they negotiate more collaboratively, set higher goals for themselves, persist at difficult tasks longer, evaluate themselves and others more favorably, help others more, and demonstrate greater creativity and curiosity than people assigned to experience neutral or negative emotions.
