What an overly aggressive reply. But sure, let’s play.

Would you look at this, a 1981 Narcotics Anonymous pamphlet that contains the exact quote: “[…] Insanity is repeating the same mistakes and expecting different results.”

Hmm… 1981… But the book was released in 1983… But your previous comment so eloquently said I’m totally wrong, so you’ve just proven time machines exist! How cool! Einstein would be proud!
