The power of words.

One day, young Thomas Edison returned home from school and handed a letter from a teacher to his mother. The mother read the letter to her son out loud, with tears in her eyes: "Your son is a genius. This school is too small, and there are no teachers here who can teach him anything. Please teach it yourself.”

Many years after his mother’s death (Edison was already one of the greatest inventors of the century at that time) he once reviewed the old family archives and stumbled upon this letter. He opened it and read, “Your son is mentally retarded. We can no longer teach him in school with everyone. So we recommend you teach it yourself at home.”

Edison wept for a few hours. Then he wrote in his diary: "Thomas Alva Edison was a mentally retarded child. Thanks to his heroic mother, he became one of the greatest geniuses of his century.
