What do You Mean by Self Image?
Your self-image is the mental picture you have of yourself. It started to be formed the moment you were born. By the age of five or six your self-concept, the person you think you are in relationship to others, is so firmly established that you will resist efforts to change it.
This does not mean you can’t change it. Many people have moved from a negative to a positive self-image and from a positive to a negative self-image. It’s just that once you get an idea of who you think you are, you don’t change very easily. And since your self-image affects every responsibility and relationship that you have, it is very important to acquire a healthy self-image as early in life as you possibly can.
