It was written on a friend's Facebook page last night:
"If you spend more time enjoying the works of geniuses, then the products of your own mind won't be inane. Trust me, before I developed my manic reading habits, I didn't have much in the way of interesting thoughts, insight, etc. I would imagine it is similar with any kind of art or thinking. Your mind is what your mind eats."
I think that last sentence should be a bumper sticker. It's definitely my new motto.
