German poet Heinrich von Kleist once wrote to his sister in 1799 that happiness cannot be proven like a mathematical theorem; it must be felt to exist. Despite this, researchers have spent decades exploring what happiness means and how to achieve it. Dorothee Salchow, a life coach trained in positive psychology, emphasizes that sustained happiness is more than luck-induced joy, but rather a state of well-being rooted in positive emotions, strengths utilization, purposeful living, goal achievement, and healthy relationships. Studies show that experiencing positive emotions, knowing and using personal strengths, having a sense of purpose, setting and achieving goals, and cultivating supportive relationships are key factors in enhancing happiness. Conversely, focusing solely on immediate pleasure, rather than meaningful experiences, can hinder long-term happiness.
