I sort of have two other words, self-worth and confidence. I probably made up my own definitions since I can't understand other people's thought processes. For me self-worth is something we all should have, as worthy people, like no one is better than the other. But self-worth can get damaged so people see themselves as inferior.

Confidence for me is how I expect to handle a task. Sometimes I know exactly what I can do, sometimes I expect a little much of me, and sometimes things go better than expected.

I assume people basically say what I think is self-worth is self-esteem, which makes sense in theory, but when people talk about self-esteem they seem to mix other things in.
