What is Habitual Error and How it happens?

There is a famous saying that a dog’s tail cannot be straightened no matter how many years we try doing it. Similarly, there are people who try their best and even pretend or decide to change, especially when the situation is critical. However, after the situation is resolved they go back to their old means. This is referred to as a habitual error that has set in a person. It is very difficult to get rid of habitual error as the person has become comfortable with the error and is not willing to take responsibility to come out of it. This is the first kind of people who cannot be changed.
