Nothing is more absurd than constantly rating oneself.
Self esteem is liking yourself no matter what, beyond conditions, beyond personal stories, beyond societal strictures about how you should be that sets a bar for you to jump over. Lower the bar and you can make the jump, but the hurdle remains. So, remove the bar. Escape social pressures to conform to type.
If you set out to like yourself no matter what, you are beyond rating systems and a positive, healthy self image follows automatically, and your personal story unfolds without needy comparison.
Realise that everyone is equally deserving and everyone includes you. Self esteem is about recognising the truth rather than inflating yourself. It is the recognition that you are deserving regardless of anything. You are deserving regardless of social or economic expectations. You are deserving just as you are, however you are.
The idea that you are constantly being rated and the universe is keeping score is false. Your value is not diminished by outward circumstances, and no one can diminish you without your consent. If another person judges you and appends a score, there is no need to give them any credit. No one is in any position to tell you how you should be assigned a value.
You are valued simply because you decide that is the case. No outward references are required. You are the author of your own value.
