We're always chasing something—be it a promotion, a new car, or a significant other. This leads to the belief that, "When (blank) happens, I'll finally be happy."
While these major events do make us happy at first, research shows this happiness doesn't last. A study from Northwestern University measured the happiness levels of regular people against those who had won large lottery prizes the year prior. The researchers were surprised to discover that the happiness ratings of both groups were practically identical.
The mistaken notion that major life events dictate your happiness and sadness is so prevalent that psychologists have a name for it: impact bias. The reality is, event-based happiness is fleeting.
