Just so you know, if you’re a person who is going through life without true sense of meaning, purpose and zest, the news is not good for your longevity. People who are happy, resilient and optimistic live longer and live healthier. And while some people may be born with sunny dispositions, happiness isn’t necessarily based on genes or luck. Psychologists now believe it’s a learned skill, almost like bike-riding. In fact, Harvard’s ‘how-to-be-happy’ course, with more than 850 enrollees, has become the university’s most popular class. Its first lesson? Embrace your failures and frustrations. “When you give yourself permission to be human,” says the course instructor and psychologist, “you are more likely to open yourself up to positive emotions.” (US News)
