"Positive self-esteem operates as, in effect, the immune system of the consciousness, providing resistance, strength, and a capacity for regeneration. When self-esteem is low, our resilience in the face of life's adversities is diminished. We crumble before vicissitudes that a healthier sense of self could vanquish. We tend to be more influenced by the desire to avoid pain than to experience joy. Negatives have more power over us than positives."
