Self-esteem = how much we like ourselves.

How much we like ourselves = level of self-dominion.

What is self-dominion? It is our ability to get ourselves to actually do, what we want ourselves to do; in other words, self-discipline and self-trust.

A person who has dominion over themselves has self-integrity - staying true to their words and commitments.

Every time we fail to listen to our inner voice, and do not take action in something that we need to, we lose trust with ourselves and our abilities. This lack of self faith continues to spiral downwardly as we flounder to fulfill more commitments.
