The way people hold to the belief that a fun­filled，pain­free life equals happiness actually reduces their chances of ever attaining real happiness.If fun and pleasure are equal to happiness，then pain must be equal to unhappiness.But in fact，the opposite is true.More often than not，things that lead to happiness involve some pain.

As a result，many people avoid the very attempts that are the source of true happiness.They fear the pain inevitably (不可避免地) brought by such things as marriage，raising children，professional achievement，religious commitment and self­improvement.

Ask a bachelor (单身汉) 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.Certainly，commitment is quite painful.The single life is filled with fun，adventure，and excitement.Marriage has such moments，but they are not its most distinguishing (显著的) features.

Couples with infant (婴儿) children are lucky to get a whole night’s sleep or a three­day vacation.I don’t know any parent who would choose the word fun to describe raising children.But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations.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 who are always having so much fun actually may not be happy at all.
