Many years later, after his mother's death, he stumbles upon an old box filled with mementos. Inside, a carefully folded letter.
It's the one that the schoolteacher gave him as a child.
He unfolds it, reads it… and discovers with astonishment these words: “Your son is incapable. He is mentally deficient. We refuse to allow him to return to school.”
That child was Thomas Edison.
He cried for hours.
Then he wrote in his diary:
"Thomas Edison was a child considered deficient... who, thanks to an exceptional mother, became a genius."
This is a magnificent illustration of what is called the Pygmalion effect: the way we look at a human being can transform their destiny.
