From Emerson's Essays, by Ralph Waldo Emerson
For no man can write anything who does not think that what he writes is for the time the history of the world; or do anything well who does not esteem his work to be of importance. My work may be of none, but I must not think it of none, or I shall not do it with impunity. -- Ralph Waldo Emerson, "Nature", p. 293
