I have a friend who is fond of saying, "What you think of me is none of my business." In other words, don't try to find out what others think of you and when you do find out, don't let it define you.
That's easier said than done. Each of us has engaged in impression management, whether we admit it or not. Some of us try to appear to be better than we are. Others seek to appear worse, but we care what others think of us.
The problem with impression management is that it is a trap. We end up losing touch with our true selves and we don't even know it. We think we actually are the character we have chosen to play.
Somehow we have to find a way to get to know our true selves and learn to live as authentically as possible. Then we can say with my friend, "What you think of me is none of my business."
