Don’t confuse vers libre and Imagism. The two are not identical. One pertains to verse, the other to vision.
Don’t attempt to “place” Imagism until you know what it is.
Don’t substitute irritability for judgement.
Don’t attempt to establish absolutes—positive or negative—by precedents of a half or a quarter of a century, or a mere decade ago.
Don’t be a demagogue.
Don’t try to speak the last word—you can’t.
Don’t be dishonest with yourself. Analyze your own inhibitions.
Don’t believe that beauty is conventionality, or that the classic poets chose only “nice” subjects.
Don’t forget that the age that produced the cathedrals produced also the grotesques.
Don’t be afraid to expand.
