Into the wild is about a man who lives in Alaska by himself with nothing to use but his mind and resources he found along the way. He was thought of as a crazy person but when people studied him they saw him as a pretty average guy.
Ralph Waldo emerson wrote a short story called from nature. It is about a man who is only when he is alone with nature. He feels worthless when he’s around people he’d rather be alone in the woods just observing to feel the happiness he really feels he deserves.
