What you are, what you think you are and what others think you are, are all different. What is the real you? What you think you are is shaped by what you think others think of you. You have developed a way to think of yourself that you would like others to adopt. Unfortunately, other people experience you and they have their own ideas about what you are. Sometimes they will think better of you and sometimes they will think worse. Mostly what they think of you is all tied up in what they think of themselves. Somewhere in there each of you has a real you that is lost in all those ideas.
In order to get a sense of the real you, you need to notice what it is that you want people to think about you. If you notice a difference between what you think about you, what you want people to think about you, and what you think people think of you, the real you lies in that difference. You are not right, they are not right, there is an unknown something in there that is the real you.
Most of our energy is spent creating and projecting and protecting an idea of ourselves that is constantly changing. Beneath it all is something, something wonderful.
