The greatest enemy of hunger for God is not poison but apple pie. It is not the banquet of the wicked that dulls our appetite for heaven, but endless nibbling at the table of the world. It is not the X-rated video, but the prime-time dribble of triviality we drink in every night.
I like living in my head because in there, everyone is kind and innocent. Once you start integrating yourself into the world, you realize that people are nasty, mean creatures. They're worse than zombies. People try to crush your soul and destroy your happiness, but zombies just want to have a little nibble of your brain.
