Who first said the definition of insanity is doing same thing and expecting different results?

The saying, "Insanity is doing the same thing over and over again and expecting different results," is often attributed to Albert Einstein.

However, there is no concrete evidence that Einstein actually said this. The phrase has been circulating for decades, but its origin remains uncertain. It's possible it originated from a paraphrase of Einstein's work, or perhaps from another source entirely.

While the origin is unclear, the saying is a powerful and insightful observation about human behavior. It highlights the importance of adapting our approach when facing challenges and recognizing when our current methods are not working.
