As long as you know what you are saying is positive and constructive. Because if you don’t desensitize yourself to criticism it will get to the point where you are so sensitive that you see negative facial expressions on other people’s faces even when that’s not actually what’s happening. Or you may even perceive authentic positive reactions as people “just faking it”. Keep a smile on your face and other people will be convinced that they’re supposed to be smiling too
