"...to have greater self-awareness or understanding means to have a better grasp of reality. Now, the opposite of reality is to project onto yourself qualities that are not there, ascribe to yourself characteristics in contrast to what is actually the case. For example, when you have a distorted view of yourself, such as through excessive pride or arrogance, because of these states of mind, you have an exaggerated sense of your qualities and personal abilities. Your view of your own abilities goes far beyond your actual abilities. On the other hand, when you have low self-esteem, then you underestimate your actual qualities and abilities. You belittle yourself, you put yourself down. This leads to a complete loss of faith in yourself. So excess--both in terms of exaggeration and devaluation--are equally destructive. lt is by addressing these obstacles and by constantly examining your personal character, qualities, and abilities, that you can learn to have greater self-understanding. This is the way to become more self-aware."
