“Mind your business” was called an “Eleventh Commandment” in the early 1800s.
 
   
Wikipedia: Fugio cent
On April 21, 1787, the Continental Congress of the United States authorized a design for an official penny, later referred to as the Fugio cent because of its image of the sun shining down on a sundial with the caption, “Fugio” (Latin: I flee/fly). This coin was reportedly designed by Benjamin Franklin; as a reminder to its holders, he put at its bottom the message, “Mind Your Business”. The image and the words form a rebus meaning that time flies, do your work. This design was also used on the “Continental dollar” (issued as coins of unknown real denomination, and in paper notes of different fractional denominations) in February 1776.
 
Some historians believe that the word “business” was intended literally here, as Franklin was an influential and successful businessman. Given Franklin’s history publishing aphorisms, it may have been intended to mean both monetary and social business.
 
The reverse side of both the 1776 coins and paper notes, and the 1787 coins, bore the third motto “We Are One” (in English) surrounded by thirteen chain links, representing the original thirteen colonial states.
