Self-esteem doesn’t depend on external actions or experiences. Contrarily, it is the manner of handling external actions. How you act, how you think, how you feel, every move of your personality is an expression of your self-esteem.
I like the picture of having self-esteem in each cell of our body. It makes self-esteem corporal and mental at the same time. With all our cells we live and express self-esteem. Everybody should have a highly developed self-esteem.
