Therapists' concerns include the mental and emotional well-being of their clients. They must be aware of their clients' egos, which are the sense of self-esteem and self-importance that people have. Egos can be fragile and easily damaged, so therapists must be careful to not hurt their clients' feelings or make them feel inadequate. Therapists must also be aware of their own egos, as they can be tempted to take on a superior role in the therapeutic relationship.
