William Shakespeare
Sonnet 15
When I consider every thing that grows
Holds in perfection but a little moment
That this huge stage presenteth nought but shows
Whereon the stars in secret influence comment;
When I perceive that men as plants increase
Cheered and checked even by the self-same sky
Vaunt in their youthful sap, at height decrease
And wear their brave state out of memory;
Then the conceit of this inconstant stay
Sets you most rich in youth before my sight
Where wasteful Time debateth with decay
To change your day of youth to sullied night
    And all in war with Time for love of you
    As he takes from you, I engraft you new
