When I was four years old，I broke my elbow. After many weeks in a cast (石膏) I returned to the hospital to finally have it removed. My mother found it strange that I was so enthusiastic about returning to the place where I had experienced so much pain. Yet she soon discovered my fas­cination with the healing process and how doctors helped to enhance it.

I was in fear as the doctor removed my cast and asked me to move my arm，and immediately became scared as the pain came shooting back through my elbow. After another series of X-rays and examinations my arm was put into a new cast I had begun to doubt the reliability of the doctor，and my mother thought I would be unwilling to return a second time.

When the day came to have my cast removed again，I was nervous. Yet I was optimistic enough to trust the doctor as he once again removed my cast and asked me to move my arm. And this time it was better! Nothing hurt!

On the way back home I released (松开) my mother's hand and ran ahead，and out of her sight. She was immedi­ately worried that I would come upon someone dangerous. At the age of four I was already known for liking to talk with strangers that I felt were potential friends. When she caught sight of me again， I was looking up into the face of an old broken-legged man，saying，“Don't worry，sir! The doctor will fix your leg. Look how he fixed my arm！” 

Since then I have continued to be fascinated with the human body and medicine. I also still love to help people，and never miss an opportunity to encourage someone. But most of all，I still believe that optimism and trust are the building blocks of happiness and success. Many things can change，but I am proud to say that these parts of me have always stayed the same.
