     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 suppertime, 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

nickel. It was the first nickel 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.
