Inter spem curamque, timores inter et iras
Amid the hope and worry, the fear and anger

omnen crede diem tibi diluxisse supremem:
believe that each day which breaks is your last:

grata superveniet quae non sperabitur hora.
the unhoped for hour will be a welcome surprise.

(The above three lines appear in Horace's "Epistles," Book I, Epistle
IV, lines 12-14, and have been quoted in various places such as
Enya's "Pax Deorum.")
