Individuals with ordinary intelligence or higher can theoretically develop into mentally healthy adults. Obviously, parents, educators, and other adults can do a great deal to ease or complicate the path to Self Esteem. Occasionally, when severe mental wounds and traumas remain unresolved from childhood, achieving a reasonable level of Self Esteem can be quite challenging. Therapy may be required in certain instances. However, I have never known someone who was completely devoid of Self Esteem or who was incapable of growing in Self Esteem, providing that sufficient learning environments exist in their world space.
