     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 a lot 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 at 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 good 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.

     If you notice them you can see that happiness is always around you. Happiness is not the same as money.

It is a 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 meet with difficulties, you can say loudly you are

very happy because you have more chances to challenge (挑战) 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) door. When it closes it also

opens. If you take every chance you get, you can be a happy and lucky person.
