      On a Friday night, a poor young violinist (小提琴家) was playing his violin at the entrance of the subway

station. The music was so great that people slowed down to listen and put some money into his hat.

     The next day, the violinist came to the entrance again. He put down his hat as usual. Beside the hat was a

piece of paper with some words on it. It said, "A George Sang has put an important thing into my hat by mistake. Welcome to claim (认领) it." Soon the people were all attracted by the words and wondered what it could be.

After a while a man rushed through the crowd, took the violinist's shoulders and said, "I knew you would

certainly come here." The violinist asked, "Did you lose something?" "Lottery ( * * )." The violinist took out a

lottery ticket with Sang's name on it and danced happily.

     Sang was an office worker. He bought the lottery and won a prize of $500,000.But when he gave $50

to the violinist for his wonderful music, the lottery ticket was thrown in, too. The violinist was a college

student. That morning, he was going to fly to Vienna for high-education. However, when he found the ticket,

he cancelled the flight and retuned to the entrance.

      Later someone asked the violinist why he didn't take the lottery ticket to pay the tuition fee (学费). He said

"Although I don't have much money, I live happily. If I lose honesty, I won't be happy forever."

     If you are a 50-year-old man, consider yourself lucky, because you are in the middle of your life now

and good things are coming your way. Have you checked yourself lately? Are you happy, healthy and

moving forward in life? If your answer is yes, congratulations, because you are blessed(有福的) and you

must be thankful. If your answer is no, then maybe my story can give you some inspiration.(启示)  

     When I was in my 20s , my life was full of fun. At that time , my aim was studying and trying to make

out what I would do when I got to my 30s . In my 30s, life became a challenge(挑战). I had to prove to

the world that I could make a difference in my life. I always kept two jobs so that I could keep going after

my dreams. I also tried studying while making a living. It was not easy, but I made it when I reached 45

years old.

     Now I'm in my 50s,I continue to move forward and look at my life positively. To all the people who are

in their 50s and more, take my advice---it is never too late to do anything. Ask yourself: after all these

years of working and living, what have you accomplished? If you think you have done well, then how you

improve yourself and grow even more? If you don't think you have done anything big in your life, it is time

to stop to think and improve yourself.
