Sweet Beatrice, wouldst thou come when I called thee? BEATRICE Yea, signior, and depart when you bid me. BENEDICK O, stay but till then! BEATRICE 'Then' is spoken; fare you well now... (Much Ado About Nothing)
Writing well isn't just a question of winsome expression, but of having found something big and true to say and having found the right words to say it in, of having seen something large and having found the right words to say it small, small enough to enter an individual mind so that the strong ideas of what the words are saying sound like sweet reason.
[L]ike thee to those in sorrow, Comes to bid a sweet good-morrow To the rough year just awake In its cradle on the brake. The brightest hour of unborn Spring, Through the winter wandering, Found, it seems, the halcyon Morn To hoar February born.
