lights halt cars for five seconds, in every direction, before turning green. Think about that. Five seconds to pause..before continuing onto your destination. Even now, you may be halfway reading this, halfway planning on what to do next; living in a perpetual state of coming and going.
"Just as one spoils the stomach by overfeeding and thereby impairs the whole body, so can one overload and choke the mind by giving it too much nourishment. For the more one reads the fewer are the traces left of what one has read; the mind is like a tablet that has been written over and over. Hence it is impossible to reflect; and it only by reflection that one can assimilate what one has said. If one reads straight ahead without pondering over it later, what has been read does not take root, but is for the most part lost." -Arthur Schopenhauer
