Hi, cursed "child genius" here. I understand perfectly well what you're talking about. These days I enjoy picking up new skills despite being absolutely terrible at all of them, (though I still do have that emotional need in the back of my mind to hide my terribleness at something when starting out learning to do something,,,,,,,,).
Do you want to improve at something or not? If you do you, you already know that implies you are shit at it. Embrace that. You're a beginner. You don't get to use that excuse as often 6 years down the line. Be bad. Play with that badness. An infant doesn't care, and infant just does. Turn off the brain.
Hopefully, six years down the line in a skill you would have gained enough confidence to just be able to do it, despite not yet being world class in that thing :p. In the end, you'll never be "good enough" for yourself no matter how good you are — at least that's how I personally feel about most of my 'skills'.
If you believe you're good enough at something you'll never have the drive to improve, and you'll plateau and be stuck at that level with for life. This is also why I feel early performers who get 'rewarded' too early by being branded as geniuses almost always get overtaken by the "untalented".
I've recently watched this video whilst looking at resources for drawing fundamentals, and I think it's applicable to more than just drawing; I do find a balance of play (with the expectation and acceptance of failure!) and active learning is a good combination for most things.

There is a well known bias of attribution when watching how others learn things called the trait ascription bias (This is a type of actor-observer bias).
We tend to make more personal attributions for the behavior of others than we do for ourselves and to make more situational attributions for our own behavior than for the behavior of others.
i.e. One would often attribute other's people speed of learning as an intrinsic part of them as a person. One would ascribe it as their personal trait. Whereas one in oneself would perceive one's own learning as something one actively does as the situation allows, with more nuance and more caveats.
I could give personal examples of this if desired.
