Seems like you’ve asked this before
Make games and teaching others is the best way to learn, check out some game jams like Godot Wild Jam happens pretty often.
Do you have an itch account? Show off your stuff in the Showcase.
Come back to a old game/project, a new look will help identify weak points and progress made. Take a break too, you’ll learn better if you give yourself time to forget.
Curb your expectations a bit:
I want to get good with the engine SO WELL, That I’m able to comfortably work on any game without having to struggle searching for an answer or running back to the forums to ask for help (Just like my current skill level in Scratch)
It’s a big world with a lot of ideas and complications; even the pros search for help daily if not by the minute. One of my favorite features of godot is the built-in docs, I can find help without even leaving the window. You get better when standing on the shoulders of giants, it’s how any of this stuff got here.
