The Law of Familiarity reads: “All things of value will, with the passage of enough time, be taken for granted.” It is very difficult to keep intensity for a long period of time.
This is true in driving a car. When we first drive, we are so cautious. We keep our hands at 10 & 2. But it’s not long before we are turning on the radio, reading the newspaper, or talking on the phone. Someone saw a bumper sticker that said, “Hang up and drive!” They also saw another bumper sticker that said, “Cats, the other white meat.” (If you stay alert it is amazing what you’ll see.)
