Drive a nail home and clinch it so faithfully that you can wake up in the night and think of your work with satisfaction - a work at which you would not be ashamed to invoke the muse.
Henry David ThoreauThe government of the world I live in was not framed, like that of Britain, in after-dinner conversations over the wine.
Henry David ThoreauI never found the companion that was so companionable as solitude. [It allows you to] be the Mungo Park, the Lewis and Clark of your own streams and oceans; [to] explore your own higher latitudes; [to] be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought.
Henry David Thoreau
