We’re all human. We don’t like criticism, or being told we are doing something wrong. Some have a tendency to over apologise, some get defensive, some get offended… However none of these reactions are productive when things need to get done.
We have a band leader. He is our director. He needs to guide us. If every time he tells us to change something or do it differently we give a year of excuses time is wasted and progress not made. It is important to learn that even though maybe you only did it that way because whatever, and you know what he’s saying, but you did it because something or other, but etc. that generally… It is most productive to just say: OK and get to it.
