Attempts to develop confidence often fail because they revolve around projecting a positive self image or achieving success. Unfortunately these two things don’t eliminate other beliefs causing feelings of insecurity. To overcome the feeling of insecurity effectively it is necessary to identify and eliminate the beliefs that generate feelings of unworthiness, fear, and anxiety. It is not enough to just cover them up with positive self images. That won’t achieve a solid feeling of confidence as long as the beliefs connected to insecurity are still intact in our mind.
