+From fairest creatures we desire increase,

+His tender heir might bear his memory:
+But thou contracted to thine own bright eyes,
+Feed'st thy light's flame with self-substantial fuel,
+Making a famine where abundance lies,
+Thy self thy foe, to thy sweet self too cruel:
+Thou that art now the world's fresh ornament,
+And only herald to the gaudy spring,
+Within thine own bud buriest thy content,
+And tender churl mak'st waste in niggarding:
+Pity the world, or else this glutton be,
+To eat the world's due, by the grave and thee.
