What is the difference between self-confidence and arrogance?

Self-confidence is a mark of attainment if a justly earned level of skill, accomplishment, and personal development in knowledge and wisdom. Such individuals are competent and effective and maintain a good balance in serving others as well as the self. This is how one is in alignment with the divine path, to have a balanced life in these ways. The arrogant individual is one who lacks some or many of those attributes but wants the prestige, opportunities, and recognition nonetheless. It is a sense of entitlement, an exaggerated sense of self-importance, and the hallmark of the absence of a connection to the divine, someone becoming very ego-based and thereby caring only about themselves and having no concern or compassion for others. This gives rise to arrogant attitudes and conduct of all kinds because a person, through ego, simply wants to have what others have and will take it from them, given an opportunity, with no concern for the feelings of others, the fairness or lack of fairness in their actions because that entitlement is so strong they will feel fully justified doing almost anything to come out on top, and will go to almost any length to bring that about no matter the consequences to others and who they hurt and how much damage results. They lack the sensitivity to have any sense of proportion about the consequences of their effect on others and this makes them quite dangerous as well as difficult to live with.
