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
  To: himself

When forty winters shall beseige thy brow,
And dig deep trenches in thy beauty’s field,
Thy youth’s proud livery, so gazed on now,
Will be a tatter’d weed, of small worth held:

Then being ask’d where all thy beauty lies,
Where all the treasure of thy lusty days,
To say, within thine own deep-sunken eyes,
Were an all-eating shame and thriftless praise.

How much more praise deserved thy beauty’s use,
If thou couldst answer ‘This fair child of mine
Shall sum my count and make my old excuse,’
Proving his beauty by succession thine!

This were to be new made when thou art old,
And see thy blood warm when thou feel’st it cold.
