Happiness is an elusive state of mind that everybody spends their lives searching for. Although grading systems such as the happiness index can aid us, happiness is not something that can be weighed or 1 (衡量), and does not "come from" anything e 2 from within our minds. Someone who c 3 fulfills the happiness index’s characteristics could quite easily be very d 4 , for example, while the homeless man with no family and ill health could just easily be the happiest man in the world. T 5 traits of a happy person such as those stipulated in the happiness index can even make people feel unhappier if they fail to meet these 6 (标准). So do not d 7 if your life seems a mess! Nobody’s life is 8 and everyone has problems to h 9 every day. So remember it is not a question of where to find happiness, but r 10 how to find it.
