"Substitute 'damn' every time you're inclined to write 'very'; your editor will delete it and the writing will be just as it should be." -Mark Twain, author and humorist (1835-1910)
Twainquotes.com has more of his writing quotes, but oddly doesn't have the one above. The Mark Twain Wikiquote site does, though. There's also Mark My Words, for those of you who like your quotes on paper.
