That quote's insanely great. It's insanely true. It's similar to some other quotes I read recently, that basically we control our thoughts and interpretations of events, not the events themselves. Therefore, we have tremendous power over our reality, but we must control our minds to use this power. If our control slip and we become irritated, it helps to realize and to remind others that the irritating person is insane. Not insanely great. Just insane.
