I have never had low confidence in anything. That is, despite extreme chronic abuse for most of my life and failing at most things.
Basically, I never had any interest in doing what other people did, had no appreciation of their praise or concern about their condemnation.
If I wanted to do something I did it. If I couldn't get it right, I would carry on trying until I did get it right. If I couldn't I just gave up. Never felt any shame in doing so.
My need to do and not to do came from within. I think there is something to the theory that leaders drive from inside and followers from outside. Or maybe it was just all the abuse or the autism. I don't know.
