“Your mind is not just the wonderful power house that empowers your action and steps or the driver of your life but a wonderful city. A city in which people and things you think about dwell. Create therefore an effective and efficient licensing office in the city of your thought that will ensure that the right people and things live there. Do well to ensure that you differentiate between people and things that should stay permanently, those that should be just passersby and that which should not even get closer to this wonderful city. If you allow anything at all into this city, the city shall be filled with anything at all and you shall think about anything at all. Mind your mind!”
