Are you aware of the notion that expressed confidence tends toward being inversely proportional to competence? And that this is a key to insightful learning?
You've said you're a young developer, so perhaps you haven't recognized this aspect of mind yet, but there's plenty of solid science (as well as anecdotal examples such as your confidence/competence in this exchange may be) that corroborate the essential truth of this aspect of mind.
Of course, I may well be wrong about applying that knowledge to this scenario, so I'm not going to claim confidence or competence in applying it, just that it seemed apropos. :)
