     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 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

good care of your life and your health; when you get a 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 doesn't mean money. It is a feeling of your heart. When you are poor, you can also say

you are very happy, because you have something 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. 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.
