Dare to be wise! Begin! He who postpones the hour for living aright is a bumpkin waiting for the river to stop.
Sapere aude, incipe. Vivendi qui recte prorogat horam, rusticus expectat dum defluat amnis.
Quintus Horatius Flaccus (Horaz) – Roman writer (65-8 B.C.), from “Epistularum liber primus” (c. 20 B.C.)
