Another person’s enthusiasm was what set me moving toward the success I have achieved. That person was my stepmother.
I was nine years old when she entered our home in rural Virginia. My father  __36__  me to her with these words: “ I would like you to meet the fellow who is ­­­­­__37__ for being the worst boy in this country and will probably start throwing rocks at you no __38__ than tomorrow morning.”
My stepmother walked over to me, __39__ my head slightly upward, and looked me right in the eye. Then she looked at my father and replied, “You are __40__. This is not the worst boy at all, __41__ the smartest one who hasn’t yet found an outlet(释放的途径) for his enthusiasm.
That statement began a(n) __42__ between us. No one had ever called me smart. My family and neighbors had built me up in my __43__ as a bad boy. My stepmother changed all that.
She changed many things. She __44__ my father to go to a dental school, from which he graduated with honors. She moved our family into the county seat, where my father’s career could be more __45__ and my brother and I could be better __46__.
When I turned fourteen, she bought me a secondhand __47__ and told me that she believed that I could become a writer. I knew her enthusiasm, I __48__ it, and I saw how it had improved our lives. I accepted her __49__ and began to write for local newspapers. I was doing the same kind of _ 50__ that great day I went to interview Andrew Carnegie and received the task which became my life’s work later. I wasn’t the __51__ beneficiary (受益者). My father became the __52__ man in town. My brother and stepbrothers became a physician, a dentist, a lawyer, and a college president.
What power _53__ has! When that power is released to support the certainty of one’s purpose and is __54__ strengthened by faith, it becomes an irresistible(不可抗拒的) force which poverty and temporary defeat can never __55__ .
You can communicate that power to anyone who needs it. This is probably the greatest work you can do with your enthusiasm.
