Gather ye rosebuds while ye may,
Old Time is still a-flying;
And this same flower that smiles today
Tomorrow will be dying.
-Robert Herrick, To the Virgins to Make Much of Time
----------
Had we but world enough and time,
This coyness, lady, were no crime.
-Andrew Marvell, To his Coy Mistress
----------
carpe diem, quam minimum credula postero.
Seize the present; trust tomorrow e'en as little as you may.
-Horace, Odes
