Our self-esteem derives from the judgment we have of ourselves. This is a judgment that comes from the ways in which we observe and the extent to which we know ourselves. An evaluation that influences and is influenced by our perceptions, emotions and relations; and is consolidated by the appraisal of the results coming from our real experiences and our ideal expectations. When the image we have of ourselves is consistent with who we really are, then we have a balanced self-esteem. Conversely, when we perceive that who we are is very different from whom we would like to be, then our self-esteem decrease. My professional support in this area aims at facilitating a realist knowledge of self, improving one’s weaknesses and appreciating one’s strengths, towards closing the gap between the ideal and real self, and thus the achievement of good self-esteem.
