     I began working in journalism when I was eight. It was my mother's idea. She wanted me to "make

something" of myself, and decided I had better start young if I was to have any chance of keeping up

with the competition.

     With my load of magazines I headed toward Belleville Avenue. The crowds were there. There were

two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible,

making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY

EVENING POST. When it was supper time, I walked back home.

      "How many did you sell, my boy?" my mother asked.

      "None."

       "Where did you go?"

      "The corner of Belleville and Union Avenues."

      "What did you do?"

      "Stood on the corner waiting for somebody to buy a Saturday Evening Post."

      "You just stood there?"

      "Didn't sell a single one."

      "My God, Russell!"

      Uncle Allen put in, "Well, I've decided to take the Post." I handed him a copy and he paid me a

nickle(五分镍币). It was the first nickle I earned.

      Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address

adults with self-confidence, and persuade them by saying that no one, no matter how poor, could afford

to be without the Saturday Evening Post in the home.

      One day, I told my mother I'd changed my mind. I didn't want to make a success in the magazine

business.

     "If you think you can change your mind like this," she replied, "you'll become a good-for-nothing."

She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me.

      My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied

with my father's plain workman's life, determined that I would not grow up like him and his people. But

never did she expect that, forty years later, such a successful journalist as me would go back to her

husband's people for true life and love.
