If a writer will go on the principle of stopping everywhere and anywhere
to put down his notes, as the true painter will stop anywhere and
everywhere to sketch, he will be able to cut down his works liberally.
He will become prodigal not of writing—any fool can be this—but of
omission. You become brief because you have more things to say than time
to say them in. One of the chief arts is that of knowing what to neglect
and the more talk increases the more necessary does this art become.
