Analysis of The changes: to corinna

Be not proud, but now incline
Your soft ear to discipline;
You have changes in your life,
Sometimes peace, and sometimes strife;
You have ebbs of face and flows,
As your health or comes or goes;
You have hopes, and doubts, and fears,
Numberless as are your hairs;
You have pulses that do beat
High, and passions less of heat;
You are young, but must be old:--
And, to these, ye must be told,
Time, ere long, will come and plow
Loathed furrows in your brow:
And the dimness of your eye
Will no other thing imply,
But you must die
As well as I.
