The wave that’s past can’t be recalled again

From  The Love Poems (The Amores, Ars Amatoria, Remedia Amoris) by Ovid, translated by A.S. Kline.

Be mindful first that old age will come to you:

so don’t be timid and waste any of your time.

Have fun while it’s allowed, while your years are in their prime: the years go by like flowing waters:

The wave that’s past can’t be recalled again,

the hour that’s past never can return.

Life’s to be used: life slips by on swift feet,

what was good at first, nothing as good will follow.
