Is One Man's Disadvantage Another Man's Advantage?

Are there any people on Earth who are completely satisfied with their appearance, character, life and job? Even if such unique creatures exist they probably live far away from simple people whose problems include blaming themselves for all the advantages they have and even don't have. However, what we really need to think about is the real situation, and sometimes the only person who can give us an honest opinion is our... best friend! If only all people could do such things for their mistreated friends, our society would be much happier!
