From fairest creatures we desire increase,
That thereby beauty's rose might never die,
But as the riper should by time decease,
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,
According to Colin Burrow , this is most likely  another  reference to Ovid’s Narcissus: “inopem me copia fecit” (my very abundance {of contact with what I love} makes me poor) was frequently quoted from the Metamorphoses. 
 The  alliterative  “f"s in this and the previous line enhance the sense of the speaker’s emotion and suggests, perhaps, annoyance. 
 Invoking the  binary opposites  of famine and abundance is characteristic Shakespeare. These opposites are replicated later in the references to “niggarding” and “glutton”.
