An excerpt from Aphorism #197

"Do not saddle yourself with fools: he is one who does not know them, and a greater, he who knowing them, does not shake them off, for they are dangerous in the daily round, and deadly as confidants..."

Aphorism #31

"Know the lucky, in order to hold them, and the unlucky, in order to flee from them.  Hard luck is mostly the punishment of foolishness, and no disease is so catching for the mourners: never open the door to a small misfortune, for many more always creep in behind it, and greater ones, under its protection.  The great trick in cards lies in knowing what to discard: and the deuce of a suit that is trump, is more valuable than the ace of the suit that was.  When in doubt, there is safety in sticking with the intelligent and the prudent, for, sooner or later, they catch up with luck." 

When It Comes to Luck, You Make Your Own

Aphorism #21

"The art of being lucky. There are rules to luck, for to the wise not all is accident; try, therefore, to help luck along. Some are satisfied to stand politely before the portals of Fortuna and to await her bidding; better those who push forward, and who employ their enterprise, who on the wings of their worth and valor seek to embrace luck and effectively to gain her favor. And yet, properly reasoned, there is no other way to her but that of virtue and attentiveness: for none has more good luck, or bad luck, than he has wisdom, or unwisdom."
