When I was a junior high school student in 1980, God gave me a gift - it was happiness. One weekend, I went to visit my grandparents in the countryside.
Several days later when I woke up at the hospital, I realized I had to spend the rest of my life without arms. I was full of fears. But slowly I knew I had to face the fact and got over it. I couldn't get my arms back even though I cried every day.
However, it's easier said than done. I got so much from my past story. From then on, I could treat my life with a normal mind. But in our daily life, I often see my classmates get worried about little things：; their bus comes late; they don't have a mobile phone but others have. But I only enjoy life. I was lucky to realize from an accident：It's a waste of our life to focus on what you have lost. We should always think of what we have. So why are so many people unhappy? Someone may say, "My whole life would improve if I have a new car. " But when you get the car and what happens? For a whole week you are walking on air. Then you go right back to being unhappy.
It's in our heart. It's a state of mind, even though you own the whole world, you may still feel unhappy. Happiness comes from mastering the art of appreciating（感激）and taking pleasure in what you really have.
| A. Happiness depends on（取决于）what we have. B. They get bad grades on a test. C. How sad I felt at that time! D. On my way home a car hit me and I was badly hurt. E. It took me nearly half a year to get out of the sadness completely. |
