Is finding other people mistakes the easiest thing to do?

During my MBA days, I was on-the-job trainee in an advertising agency. Over there, I use to write body copy for the clients. My boss (who was also an owner of the agency) used to have many observations, corrections, and changes in everything I submitted. I started thinking that is he trying to show me how smart he is, or is he is genuinely adding value?

Once there was a press conference organized for a client, and my boss wanted me to have poster placed at the conference . He pulled out a piece of paper wrote the content and asked the design team to print the poster. I took the poster and rushed to the venue. As I was placing it, I realized that there are at least three things we could have done better in the poster's content & design.

At that very moment, I realized that finding other people mistakes is the easiest thing to do, and doing it, does not add any value to us as an individual.

If we want, we add value to ourselves and others by doing either of the two. Number one, if the issue is not big, we add value to our self by keeping our opinion to ourselves, we learn self-control and self-analysis. Secondly, if we believe in our observation and convinced about it , we will add value to other person by sharing our opinion in a constructive way, while understanding other persons viewpoint , in the overall process making “things “better.
