It is a mistake to look at someone who is self assertive and say, "It's easy for her, she has good self-esteem." One of the ways you build self-esteem is by being self-assertive when it is not easy to do so. There are always times when self-assertiven ess requires courage, no matter how high your self-esteem.
Nathaniel BrandenStressing the practice of living purposefully as essential to fully realized self-esteem is not equivalent to measuring an individual's worth by his or her external achievements. We admire achievements-in ourselves and others-and it is natural and appropriate for us to do so. But that is not the same thing as saying that our achievements are the measure or grounds of our self-esteem. The root of our self-esteem is not our achievements but those internally generated practices that, among other things, make it possible for us to achieve.
Nathaniel BrandenWhat is guilt? It is moral self-reproach-I did wrong when it was possible to have done otherwise.
