What is self concept?

It is the way a person views him or herself, and includes things like self esteem, self image, family roles, identity, values, religion, occupation, philosophy, goals, or whatever is important to the person in how he or she views him or herself.

The way you view yourself is your self-concept. Concept means idea so your self-concept is the idea that you have about yourself. The way you see yourself, of course, may be completely different to how others see you.
