     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 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 a bit of 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 yourself. So you cannot always say you are poor and you have bad luck. As the saying goes,

"Life is like a revolving door. When it closes, it also opens. If you take every chance you get, you can be

a happy and lucky person."
