People often believe that achieving specific goals or milestones like getting a perfect job, higher salary, or certain accolades will lead to lasting happiness. However, studies show that while these achievements do bring temporary happiness, it doesn't last. Lasting happiness comes from understanding that our minds deceive us about what truly makes us happy. Many individuals fall into the 'happy if or happy when' mindset, constantly seeking happiness in future events like promotions, relationships, or material possessions, only to realize that happiness remains elusive even after achieving these goals. This tendency is known as the arrival fallacy, where people believe that they will be happy once certain conditions are met, but in reality, true happiness comes from within and requires a deeper understanding of what genuinely brings fulfillment.
