Thomas Edison, the inventor who thought he could, as he often said, "Concentrate all the news I encountered or thought I ought to recollect within these brain cell walls." Little did he know, his optimism would lead to the creation of the first practical incandescent light bulb, the phonograph, and the kinetoscope.
His optimism was not just about inventing, it was about changing the world. He was the embodiment of the phrase "I have not failed. I've just found 10,000 ways that won't work."
