Carl Rogers' notion of self and self-actualization is described in his text "A Theory of Therapy, Personality, and Interpersonal Relationships." In this text, Rogers describes the notion of the self as when an individual "has the ability to guide, regulate, and control himself."
According to Rogers, one must be able to do the following in order to self-actualize:
1. be able to express emotions;
2. rely on their decision making abilities;
3. accept responsibility for the actions they choose to make;
4. must possess regard that is positive for those around him/her.
It is only when a person is able to do these things that Rogers would consider them to be fully self-actualized.
