In fact,      is always around you if you put your heart into it. When you are in         at school, your teachers will help you; when you do something wrong, people        you feel unhappy; when you        in something, your friends will say congratulations to you. All these are your happiness. If you notice a bit of them, you can see       happiness is always around you.

Happiness is not the same as money. It is a feeling of your heart.      you are poor, you can also say you are very happy. Money is not       . 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       . 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.
