We are always learning and changing. We learn from each other. It is hard on someone to be accepted only when they please others. Power grows in us the moment a future dream transforms into present day action. Peer facilitators can help people change.
Nothing influences the development of our self-concept more than the consequences of our behavior.
I might also said that it is more specific to say that it is the resulting feelings which not so much the results of our behavior. This was independent of the counselor's theory and technique. People are changed very little by advice, persuasion or threat. We experience the most change when we are with a helping person who is positive, understanding, tolerant, easy to talk with, non-judgmental and who cares about us. The relationship between the helper and the helpee can be a positive catalyst in its own right.
