How I feel about and behave ...

How I feel about and behave toward myself is the basic determinant of most of my behavior. If I improve my self-regard, I will find that dozens of behaviors change automatically. If, for example, I increase my feelings of self-competence, I will probably be less defensive, less angered by criticism, less devastated if I do not get a raise, less anxious when I come to work, better able to make decisions, and more able to appreciate and praise other people.

If I, the group leader, expect you, the group member, to be weak, then I elicit the weak part of you. If I expect you to be able to cope, I elicit your strength.
