I detest this quote for a variety of reasons. For one, it’s consistently attributed to Albert Einstein, who absolutely never said it—it actually comes from a 1983 fiction book titled “Sudden Death.” The quote is also annoying because there are people in this world today who think it’s the literal definition of the word.
It is not.
Third, doing something repeatedly and expecting a different result is hardly a proper example of insanity. If I’m hacking at the base of a tree with an axe over and over, I expect one of those swings will produce a different result than the first few hundred I take.
