When we describe ourselves or our personalities we may need several types of descriptions. We are not just one person, but several. Taken together, these images of ourselves make up a picture--the picture you carry around in your head about yourself. This composite image is your self-concept. It is how you see your own personality.
Many aspects of your self-concept come from the way you feel about the self you were born with--for example, your sex, physical appearance, and race. Although, you can do little to change these inborn physical features, how you look at them and how others respond to them determine, in part, your self concept. How you look at your abilities and typical responses, at all the behaviors you've acquired, also determines your self-concept--probably to an even greater degree.
