But why I changed? why I left the woods? I do not think that I can tell. I have often wished myself back. I do not know any better how I ever came to go there. Perhaps it is none of my business, even if it is yours. Perhaps I wanted a change. There was a little stagnation, it may be. About 2 o’clock in the afternoon the world’s axle creaked as if it needed greasing, as if the oxen labored with the wain and could hardly get their load over the ridge of the day. Perhaps if I lived there much longer, I might live there forever. One would think twice before he accepted heaven on such terms.

— Henry David Thoreau
