I have heard stories about how a comparison plays a role in society. From parents to a manager to a sports coach, everyone compares.
We are all biased. We have our own lens. We conclude judgment on our own ideology.
Your father might compare you with brother saying how prosperous he is with a great salary. This forgets mentioning how his money making kin is a lab rat and running after money.
Your manager might not like you because he/she thinks you are not adding value. He/she forgets your contribution with many other domains: hiring, community, management.
Your coach will not like your contribution because he/she thinks you are a good bowler. Your contribution as an all-rounder goes in waste.
One has to be very careful in handling these situations.
