Una dabit quod negat altera.
One hour will give what another has refused.

Come along and grow old with me; the best is yet to be.

Let others tell of storms and showers; I mark only the sunny hours.
Mach' es wie die Sonnenuhr: zähl' die heitren Stunden nur!

Utere non reditura.
Use the hour, it will not come again.

Utere, non numera.
Use the hours, don't count them.
