So live as brave men; and if fortune is adverse, front its blows with brave hearts

The origin of this quote is often misattributed to Cicero; however, it is from Line 135-136 of Book 2, Satire 2 by Horace, "Quocirca vivite fortes, fortiaque adversis opponite pectora rebus." The English translation that most closely matches the one misrepresented as Cicero's is from a collection of Horace's prose written by E. C. Wickham, "So live, my boys, as brave men; and if fortune is adverse, front its blows with brave hearts."
