     I live in the land of Disney, Hollywood and year - round sun. You may think People ,n such an

attractive, fun - filled place are happier than others. If so you have some mistaken ideas about the nature

of happiness.

     Many intelligent people still think fun equals happiness. The truth is that fun and happiness have little

or nothing in common. Fun is what we experience during an act. Happiness is what we experience after

an act. It is a deep, long-lasting emotion.

     Going to an amusement park or a ball game, watching a movie or television are fun activities that help

us relax, temporally forget our problems and maybe even laugh. But they do not bring happiness, because

their positive effects end when the fun ends.

     I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has

nothing to do with fun. They have constant access to exciting parties, fancy cars, expensive homes,

everything that spells "happiness" But in memoir (回忆录) after memoir, they expose Ac unhappiness

hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages and loneliness.

    Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he

is honest, he will tell you that he is afraid of making a commitment. For commitment is in fact quite

painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they

are not its most distinguishing features.

     Similarly, couples that choose not to have children are deciding in favor of painless fun over painful

happiness. They can dine out whenever they want and sleep as late as they want. Couples with babies are

lucky to get a whole night' s sleep. I don't know any parent who would choose the word fun to describe

raising children.

     Understanding and accepting that true happiness has nothing to do with fun is one of the most

liberating realizations we can ever come to. It liberates time: now we can devote more hours to activities

that can truly increase our happiness. It liberates money: buying that new car or those fancy clothes that

will do nothing to increase our happiness now seems pointless. And it frees us from envy: we now

understand that all those rich and famous people we were so sure are happy because they are always

having so much fun actually may not be happy at all.
