I must be unloveable

The child who is not loved by his parents will always assume himself or herself to be unlovable rather than see the parents as deficient in their capacity to love. Or early adolescents who are not successful at dating or at sports will see themselves as seriously deficient human beings rather than the late or even average but perfectly adequate bloomers they usually are. It is only through a vast amount of experience and a length and successful maturation that we gain the capacity to see the world and our place in it realistically, and thus are enabled to realistically assess our responsibility for ourselves and the world.
