Insanity: doing the same thing over and over again and expecting different results.
Of all the things I've lost, I miss my mind the most.
In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule.
One person's craziness is another person's reality.
It is sometimes an appropriate response to reality to go insane.
There's a fine line between genius and insanity. I have erased this line.
I became insane, with long intervals of horrible sanity.
The statistics on sanity are that one out of every four people is suffering from a mental illness. Look at your 3 best friends. If they're ok, then it's you.
The reason I talk to myself is because I'm the only one whose answers I accept.
Insanity is doing the same thing, over and over again, but expecting different results.
