Found it Curious Pussy!

TO THE VIRGINS, TO MAKE MUCH OF TIME.
by Robert Herrick


GATHER ye rosebuds while ye may,
Old time is still a-flying :
And this same flower that smiles to-day
To-morrow will be dying.

The glorious lamp of heaven, the sun,
The higher he's a-getting,
The sooner will his race be run,
And nearer he's to setting.

That age is best which is the first,
When youth and blood are warmer ;
But being spent, the worse, and worst
Times still succeed the former.

Then be not coy, but use your time,
And while ye may go marry :
For having lost but once your prime
You may for ever tarry.
