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 county 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 for his enthusiasm.” That statement began a (n) 42 between us. No one had ever called me smart.

When that power is released to support the certainty of one’s purpose and is 54 strengthened by faith, it becomes an irresistible 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.
