      "Everything happens for the best," my mother said whenever I was disappointed. "Don't worry. One

day your luck will change."

      I didn't pay attention to her words. After finishing my college education, I decided to look for a job

in a radio station. I wanted to host a sports programme. I went to Chicago and knocked on the door of

every station. But I got turned down every time.

     In one station, a kind lady said to me that I hadn’t got enough experience. "Get to a small station and

work for some time," she said.

     When I went back home, my dad told me that a businessman had opened a store and needed someone to help him. But again, I didn't get the job.

     I felt really down. "Your luck will change," Mum said to me. Later, I tried another radio station in Iowa. But the owner, a nice man, told me he had already had someone to work for him. As I left his office, I

asked, "How can someone be a sports announcer (播音员) if he can't get a job in a radio station?"

     I was waiting for the lift when I heard the man call, "What did you mean? Do you know anything about football?" He let me sit in front of a microphone and asked me to try to imagine that I was giving my

opinion on a football game, and finally I succeeded.

     On my way home, Mum's words came back to me, "One day your luck will change, Son."
