Do not speak in a situation wherever it is not necessary. As humans we tend to express a lot infront of people. I have done it many times, and felt that I shouldn’t have done it. Yes, that may be super difficult, when you notice people doing things in a wrong way, usually we try to correct them in case if we know how to do the same things better. Some people may like it and some may not. Many times I have given more information than necessary. And today I felt that it needs to be reduced significantly.
Speaking more than necessary or giving more than necessary information can backfire.
