Shakespeare Sonnet 1

Shakespeare starts the first of the sonnets directed to W.H. apparently attempting to convince the young man to start a family.  The poem begins by saying how people have a desire for beauty in the world.  The next two lines kind of say that the only way for the man to keep his beauty before he grows old and loses it is to continue his bloodline.  One interesting thing about this sonnet is that in a few lines the speaker uses some contradicting words to describe things.  "Famine where abundance lies" and "sweet self too cruel" are all used in the same respective lines which causes a bit of confusion for me.  These lines though are trying to say that the boy is really his own worst enemy and has to take action before he gets too old.  At several points the sonnet is talking about the subject as being too self-concerned and needs to learn to share, and in this case, breed.  "Within thine own bud buriest thy content, and, tender churl, mak'st waste in niggarding", Shakespeare seems to suggest with this line that the man is being selfish by not having children and in turn spreading his beauty.  He's hoarding his good looks and needs to settle down so the lineage can continue.
