“Never send off any piece of writing the moment it is finished. Put it aside. Take on something else. Go back to it a month later and re-read it. Examine each sentence and ask ‘Does this say precisely what I mean? Is it capable of misunderstanding? Have I used a cliché where I could have invented a new and therefore asserting and memorable form? Have I repeated myself and wobbled round the point when I could have fixed the whole thing in six rightly chosen words? Am I using words in their basic meaning or in a loose plebeian way?’”
Evelyn Waugh, letter to Thomas Merton, August 13, 1948 (courtesy of Anecdotal Evidence)
