Building self confidence is a very worthy endeavor. We can be confident in some areas and not in others. Wouldn't it be great to feel confident in those other areas as well? There can be unconscious reasons for the lack of confidence perhaps from childhood or an uncomfortable experience. These can stay with us until we decide to do something about it. Discovering the underlying reasons for the lack of confidence and reevaluating them can bring amazing insight into why we feel less than confident. We retrain the mind to embrace the improved and updated belief in the self. You might want to imagine it like pressing the send button to your mind computer.
