When we do something over a period of time, we don’t need to think about it next time we do the activity. It becomes automatic. This is what we called habitual pattern.
The habits and addictions that we have are stored in our subconscious mind. To eliminate them, we cannot use the conscious effort like Willpower. We need the subconscious mind to influence and affect the stored habits to make real and lasting change.
Since it is stored in the subconscious mind, the best approach is to influence the subconscious to get the desired results.
