Wendell Berry said this quote
“ He was lonely because he could imagine himself as anything but himself and as anywhere but where he was. His competitiveness and self-centeredness cut him off from any thought of shared life. He wanted to have more because he thought that having more would make him able to live more, and he was lonely because he never thought of the sources, the places, where he was going to get what he wanted to have, or of what his having it might cost others. It was loneliness that sometimes even he felt; you could see it. A self-praiser has got to accept a big loneliness in order to accept a little credit. ”
