Many times we make mistakes due to our lack of knowledge or wrong information. I see nothing wrong with that. But after making a mistake, if you do it again without learning from it, it is a sin. I think that's what the OP meant. I'm the one who always right needs to get this idea out of our minds. If someone points out a mistake, it should be corrected politely.
Everyone has made mistakes in their life, whether it be from the work they do or from ideas that they themselves have developed in their lives which ultimately must be corrected by each of them. Because other people will never correct our mistakes, we ourselves must do it politely and it also needs to be emphasized that everyone must be hard on themselves and gentle on others. Because when working and correcting mistakes, we also need more focus and precision so that we can personally become better in any case.
