When you look at yourself in a mirror, what you see depends on your mental image of yourself. If you think and accept yourself as a valued and worthwhile person this immediately is projected to your posture and the way of communication with the others. Our self-image makes a great difference about how we feel and act. Probably that is the part where I suppose to share an example, but I am not sure that my experience would be relevant to anyone else simply because this is a matter of very personal subject and what makes me feel good might be very odd or unpleasant for some one else. Self-confidence is very important for creating strong mental image and there fore makes us like what we feel and see of ourselves. Of course there are several exercises for busting the feeling of confidence but I strongly agree that nothing of this could be done if we don't really trust and believe our body and mind. And again to do so we have to except and forgive (when is necessary) ourselves and complete the circle (acceptance- self-confidence - trust in our abilities). Further more some imperfections of our body can be easily turned as strong points, if our mind manage to dictate so, and actually show us in the eyes of the others as very unique and independent person with open mind and experimental nature.
