When a person has a poor estimation of himself or herself, he/she has negative self-perception or poor self-image.
One of the symptoms such a person exhibits is lying and insulting other people in driving home his/her point; howbeit, lying is a behavioral misconduct that is associated with negative self-concept. It is important for our ‘Yes’ to be ‘Yes’ and our ‘No’ to be ‘No’, which will be easily achieved when our esteem is enhanced through positive self- perception.
