Permanent Fixtures of Your Mind
As it happens, old habits do not die. They don’t disappear. When you stop practicing them, and instead discipline yourself to behave in a new way, they become weak and withdraw into your subconscious mind. Your new habits may override and replace the old habits, but you never eliminate them completely. They lurk below the surface, waiting to reemerge at a later time, when the stimulus that originally created them is repeated.
For example, when you were young, you learned how to ride a bicycle. Eventually you began driving a car. Many years, even decades later, you can get onto a bicycle and within a few seconds, you can be riding with the same balance and skill that you had programmed into your subconscious mind as a child.
Many people first learned how to drive a car with a standard transmission, a stick shift. Today most cars have automatic transmissions. You may drive one for years. However, if you were required to drive a car with a stick shift, even after many years, you would slip into the old habit of shifting gears easily and naturally in a
few seconds. The old habits never completely go away.
