This tongue-in-cheek line “Mark Twain Said The Secret Of Getting Ahead Is Stop Misquoting Me” is actually taking a swipe at those who follow blindly and attributed the quote: “The secret of getting ahead is getting started” to Mark Twain.
Interestingly, Goodreads.com, attributed this quote to both Mark Twain and Agatha Christie.
It also appears in Agatha Christie website.
Well, I’m not the least shocked to find this unverified quote at popular sites such as Brainy Quotes and Quote Garden.
As you know they never and do not cite the sources of their published quotes.
According to Mental Floss, neither source can be verified.
