Happiness is for everyone. You don't need to care about the rich. Though they have beautiful houses with large gardens and swimming pools, they may often feel lonely.
    In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your teachers will help you; when you do something wrong, people around you feel unhappy; when you succeed in something, your friends will say congratulations to you. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
    Happiness is not the same as money. It is a feeling(感觉) of your heart. Although you are poor, you can also say you are very happy. Money is not everything. You have something else that money can't buy. When you meet with difficulties, you can loudly say you are very happy because you have more chances to challenge(挑战) yourself. So you can not always say you are poor and you have bad luck. If you take every chance you get, you can be a happy and lucky person.
