“Everything happens for the best.” Whenever I faced disappointment(失望),my mother would say this to me.

After I left college in 1932, I decided to find a job in radio as a sports announcer(广播员). I went to Chicago and knocked at the door of every station. But unluckily, I was refused every time.

At one station, a kind lady told me that big stations wouldn’t hire(雇佣)a person without any experience and suggested that I try my luck at smaller stations. Following her advice, I went back to Dixon, where I had grown up. There were no such jobs in Dixon, and my father said a newly-opened store wanted a local athlete(运动员)to work for it . I wanted this job, but I was refused again.

“Everything happens for the best,” Mom reminded me. Dad offered me the car to look for a job. I tried WOC Radio in Davenport, Iowa. The program director, Peter MacArthur, told me they had already hired an announcer.

As I left his office, I felt so frustrated(沮丧). “How can I become a sports announcer if I can’t get a job in a radio station?” I asked aloud.

While I was waiting for the lift, I heard someone calling. It was MacArthur. “What was that you said about sports? Do you know anything about football?” Then he asked me to have a try. He was pleased with my performance, and he offered me a chance to work there.

On my way home, I thought of my mother’s words: “If you carry on, one day something good will happen. Something wouldn’t have happened if without the failure before.”
