Insanity: doing the same thing over and over again and expecting different results.
Imperfection is beauty, madness is genius and it's better to be absolutely ridiculous than absolutely boring.
Disease, insanity, and death were the angels that attended my cradle, and since then have followed me throughout my life.
Insanity - a perfectly rational adjustment to an insane world.
R. D. Laing
You cannot carry out fundamental change without a certain amount of madness.
