Famous quotes containing the words life and/or force:
“Great geniuses have the shortest biographies. Their cousins can tell you nothing about them. They lived in their writings, and so their house and street life was trivial and commonplace. If you would know their tastes and complexions, the most admiring of their readers most resembles them.”
—Ralph Waldo Emerson (1803–1882)
“Happiness ain’t a thing in itself—it’s only a contrast with something that ain’t pleasant.... And so, as soon as the novelty is over and the force of the contrast dulled, it ain’t happiness any longer, and you have to get something fresh.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
