Insanity

When you hit yourself in the head with a hammer it hurts. Quite a lot most likely. But you do it again thinking maybe the next time it won't hurt. But it does hurt, just like the first time. Then perhpas you think, it could not hurt like the first two times a third time. Wrong. So you wait a week. Maybe you just need to forget the pain and try it again later. Nope, same thing, pain. A month later, happens again. You quickly remember the pain, same result. A year later. . .

Insanity is repeating the same behavior and expecting a different outcome.
