You are approaching it like a problem to solve with the mindset of somebody who is trying to get self-confidence as a step in the direction of building something or achieve results. If you manage to get the self-confidence at a sky high level you won't care about building something or achieving goals. Mentally they'd be redundant and sort of pushing on a string given that your self satisfaction is maxed out already. You can't grasp it now because you imagine a person like that as deluded and 'not going anywhere' or even worse regressing, but if you manage to get in that state of mind, you'd be the one living it and having a blast inside your own head, not being an external observer judging. If you think about it's a way of cheating Mother Nature, for the rules are that she releases endorphines and satsifaction after a job well done. The person who manages to get in that state of mind endogenously would be de-facto ambushing Mother Nature and beating her up until she releases the endorphines without anything in exchange for it.
