Jimmy Page... 14ish I think... playing Skiffle
My point?
The legends didn't start out playing {legendary solid-intermediate to advanced} ...stuff
Most of them started out as kids; with nothing more than naive affection for music > guitar
They didn't mind playing the boring pre-rock stuff...
because Rock didn't exist yet
or in the case of later greats: they were just kids.
Note:
I'm saying this partly for my self;
because as much as I intellectually know what I just said is true...
I still catch my self drifting into the overcompensating focus on things I don't need to concern my self seriously with yet.
sure: play around with that stuff... the riffs and whatever...
But until you can play anything easier than it perfectly with ease...
you haven't established the requisite skillset and fundamental understanding of how music works.
Even the cats that didn't consciously understand theory understood it subconsciously; by proxy of experience with copious amounts of music.
