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 genuinely 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 liberates us from envy：we now understand that all those rich and glamorous people we were so sure are happy because they are always having so much fun actually may not be happy at all.
