You have an internal image and an external image. Human tendency is to adjust the behavior in line with the internal or external image. Internally if you feel proud, this will reflect in your external behavior. Similarly if others expect you to behave in a particular way because of your image, you will be disappointing them if you do not act accordingly. Whenever you act out of tune with your image, there will be an urge for self correction.
Open a ‘Personal Integrity Account’ today. You operate this account just like you operate your bank account by putting a credit and debit and arriving at a balance. Every time you do an act, which you had promised, credit 10 points to your Personal Integrity Account. Whenever you do not do an activity which you had promised, debit 10 points. At the end of the day before going to bed add the credit points and the debit points and arrive at the balance. This is your Personal Integrity Account.
This simple practice will make a difference in your internal image and will result in self-correcting tendencies.
