    Happiness is a feeling that lights up your eyes, makes your steps light and makes you want to sing for no

reason. Everyone wants to be happy. But sometimes, a guest comes in without invitation. It's unhappiness.

Don't let it get you down. Send it away!

    When you are happy, the world feels like a better place. As the saying goes: When you smile, the world

smiles with you; when you cry, you cry alone. Wearing a smile will make you more charming (迷人的) and

help you to win lots of friends. A good mood always gives you hope, which makes trouble and problems

easier to handle.

    No matte how happy you are, it's normal to feel angry, sad or gloomy once in a while. Life is full of ups

and downs. We can't change the way life is, but we can do our best to change a bad situation into a good one.

To help us do this, it's good to know some of the factors (因素) that influence happiness.

    One of the biggest factors is social relationships. People who are close to family and friends are happier

than people who don't have those relationships. Talking and sharing is a good way to relax and build

confidence (信心). Knowing someone is there for you will make you braver and more outgoing.

    Another factor is work or school. If you enjoy school, even if you have lots of homework or extra classes,

you will still feel that your school life is meaningful and happy. But if you hate school, your negative attitude

may cause you to feel bored and upset that you have to do so much work.

    A third factor is your attitude towards life. How do you feel if you fail in an exam? Maybe you think it's

unfair because you always study hard and should get a good mark. You can't stop blaming yourself. Or,

maybe you accept it. You go through the paper carefully, find out why you made stupid mistakes, and tell

yourself, "Take it easy! I'll do better next time!" Your attitude makes a big difference.
