Mailgram definition of insanity

A classic!

The "definition of insanity" is a phrase that is often attributed to Albert Einstein, but there is no solid evidence that he ever said or wrote it. The phrase is often used to describe a situation where someone is repeating the same behavior or action over and over again, expecting a different result, which is often considered a hallmark of insanity.

The phrase is often paraphrased as:

"Doing the same thing over and over again and expecting different results is the definition of insanity."

Or:

"Insanity is doing the same thing over and over again and expecting a different result."

This phrase is often used to describe situations where someone is stuck in a cycle of behavior that is not yielding the desired outcome, and they continue to repeat the behavior despite the lack of success.

For example, if someone is trying to lose weight by dieting and exercising, but they keep gaining weight, and they continue to do the same diet and exercise routine, expecting a different result, that could be considered a definition of insanity.

It's worth noting that this phrase is often used in a humorous or ironic way, and it's not meant to be taken literally.
