Look in thy glass, and tell the face thou viewest
Now is the time that face should form another;
Whose fresh repair if now thou not renewest,
Thou dost beguile the world, unbless some mother.
For where is she so fair whose unear’d womb
Disdains the tillage of thy husbandry?
Or who is he so fond will be the tomb
Of his self-love, to stop posterity?
Thou art thy mother’s glass, and she in thee
Calls back the lovely April of her prime:
So thou through windows of thine age shall see
Despite of wrinkles this thy golden time.
But if thou live, remember’d not to be,
Die single, and thine image dies with thee.

William Shakespeare, Sonnet 3

Sonnet 3 Modern English translation

Look in your mirror and tell the face you see that it’s time it should create another If you do not renew yourself you would be depriving the world, and stop some woman from becoming a mother. For where is the lovely woman whose unploughed womb would not appreciate the way you plow your field? Or who is he foolish enough to love himself so much as to neglect reproducing? You are the mirror of your mother, and she is the mirror of you, and in you, she recalls the lovely April of her youth. In the same way, you will see your youth in your own children, in spite of the wrinkles caused by age. But if you live your life avoiding being remembered you will die single and your image will die with you.
