The biggest price we pay for doing something bad, even small thing, like treating one of our employees badly or being mean to someone, is NOT the negative feedback from our boss, the criticism from our partner or our parents, the punishment we get from our teacher or the low marks in school. The biggest price we pay is this internal voice, the voice of our conscience which will remind us all the time that what we did is not right. This is the biggest price we pay because while the remark of our boss or the voice of our partner or teacher will be painful to hear once, the voice of our conscience stays with us forever. It is the biggest pain because while all others’ criticism could be wrong, we know deep down inside us that the voice of our conscience is never so. It is the biggest pain because no one can damage our self-esteem without our own approval and our conscience is the only and ultimate approver.
