Today, I am wondering what would have happened to me by now, if, fifty years ago, some fluent talker had converted me to the theory of the eight-hour day and convinced me that it was not fair to my fellow-workers to put forth my best efforts in my work?

Edison informed the man that he had made 20,000 experiments but none had worked. "Aren't you discouraged by all this waste of effort?" the reporter asked. Edison: "Waste! There's nothing wasted. I have discovered 20,000 things that won't work."
