Next step is to improve the spiritual awareness of the person and make him believe that there is a power greater than the human force that will help in attaining the target. But it will not be easy to bring this tendency to a person but when it is done then, it will be very easy to control the addiction habit of the person.
Try to make him see the hidden beauties of life and try to build his self-confidence so that he gains willingness to live a successful life.
