根据短文内容回答问题。

　　Different people have different happiness．Happiness is for everyone．You don't need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and lots of money and so on．Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads in their free time．

　　In fact, happiness is always around you if you put your heart into it．When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it; and when you do something good to others, you will feel happy, too．All these are your happiness．

　　Happiness is not the same as money．It is the feeling of your heart．When you are poor you can also say you are very happy, because you have something else that can't be bought with money．When you come across difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself．So you cannot always say you are poor and you have bad luck．As the saying goes, life is like a revolving(旋转的)door．When it closes, it also opens．If you take every chance you get, you can be a happy and lucky person．
