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 an 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 a 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 problems easier to work out.
No matter how happy you are, it's normal to feel angry and sad sometimes. 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 the social relationship. People who are close to their family and friends are happier than those who don't have those relationships. Talking and sharing are good ways to relax and build confidence. 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(消极的态度) may cause you to feel bored and upset.
A third factor is your attitude towards life. How do you feel if you fail an exam? Maybe you think it's unfair because you always study hard and should have got a good mark. You can't stop blaming(责怪) 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.
Do you smile a lot or wear a long face most of the time?
