Be like a solid tower whose brave height remains unmoved by all the winds that blow; the man who lets his thoughts be turned aside by one thing or another, will lose sight of his true goal, his mind sapped of its strength.
Dante AlighieriHere we find the moat of thieves. And just as a lizard, with a quick, slick slither, Flicks across the highway from hedge to hedge, Fleeter than a flash, in the battering dog-day weather, A fiery little monster, livid, in a rage, Black as any peppercorn, came and made a dart At the guts of the others, and leaping to engage One of the pair, it pierced him at the part Through which we first draw food; then loosed its grip And fell before him, outstretched and apart.
