One's own description as a person is

One's own description of oneself as a person is called self-concept.

It is the overall picture a person holds of who they are, their traits and worth.

Self-perception is the process of noticing one's own behaviour, a narrower act than the whole self-picture.

Self-awareness is conscious attention to one's feelings and states in the moment, not the standing description.

Self-respect is the regard or esteem one holds for oneself, a value judgement rather than a description.

Self-concept forms through experience, feedback and comparison with others.
