That's not what OP said. Quote:
> Self-esteem is a byproduct of self-compassion
Self-compassion is not believing in yourself, it's accepting yourself as-is. And not just accepting in the sense of "settling for it". But having the same respect and nice feeling about you that you have about the others your like.
While outside validation helps a lot in one to avoid rejecting oneself, it just removes a (huge) barrier for building self-esteem. Self-esteem can't come from outside.
The problem with other people validating you is that as soon as you loose it, you loose what you though was self-esteem. And you get angry, you blame, you can't find solutions, and you ever give you all the responsibilities or remove yourself from all of them.
If you succeed and get praise, it then inflate your ego and narcissism.
But once you build self-compassion, even when you screw up, you still like yourself. But you can still see your fair part of responsibility in all this. And when your succeed, liking yourself as you are, you know what's really you, and what's really coming from outside help and luck. And you don't inflate your ego.
