Enduring habits I hate…. Yes, at the very bottom of my soul I feel grateful to all my misery and bouts of sickness and everything about me that is imperfect, because this sort of thing leaves me with a hundred backdoors through which I can escape from enduring habits.

Friedrich Nietzsche

Reading, after a certain age, diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking.

Albert Einstein
