I think this is a good observation about the impact that confidence can have on some (mine included) peoples ability to learn. In this way, low confidence can have both the direct effect of denying you access to information that would allow you to improve, but also more sinister, it can deny you the mental ability to actually learn something, even if the information was available to you, since the learning itself will mean that there's things you don't know. Being aware that you don't know or can't do something can feel very bad if you lack the confidence in your ability to get to know or do it, and we tend to avoid feeling bad, and so may abandon the endeavor.
