" This self-image is our own conception of the “sort of person I am.” It has been built up from our own beliefs about ourselves. But most of these beliefs about ourselves have unconsciously been formed from our past experiences, our successes and failures, our humiliations, our triumphs, and the way other people have reacted to us, especially in early childhood. "
