The beginning of our loss of self-confidence is the beginning of the recognition that we are limited in our abilities and skills, and sometimes others perform better than us in certain tasks.  We may also compare our physical appearance, strength, voice, income level, and so on unfavourably with another, and put ourselves down (inappropriately) for our "poor showing".  The destruction of our self-confidence begins when we decide "I am an X and I should be a Y", where X and Y can be any juxtaposed qualities, traits or personality features, or identification with particular behaviours.  The beginning of self-confidence is the recognition that I am okay, and you are okay, just the way we are; and just because we choose to define ourselves in that way.  That we are not our traits or behaviours.  That we are the aliveness that animates these bodies of ours, and that we all have our own "acres of diamonds", or our pools of talents, which we can develop, regardless of what other people think of us or our abilities.

I can help you to track down the mistakes you are making in your thinking which are undermining your sense of self confidence, and how to change from being an "effect" of the perceptions of others to being a "cause" of your own self-concept.
