“I have ever since been tortured by the fear that what I write is not my own. For a long time, when I wrote a letter, even to my mother, I was seized with a sudden feeling, and I would spell the sentences over and over, to make sure that I had not read them in a book. It is certain that I cannot always distinguish my own thoughts from those I read, because what I read become the very substance and texture of my mind.”
— Helen Keller
