Information overload and choice paralysis ruins me I need help...I always feel incompetent

I'm an artist and struggle with learning new concepts, atm it's backgrounds and perspective I'm hit a wall where it feels like I have too much to think about and no idea how to choose my next path.

I want to learn perspective and how to draw backgrounds for comics but my brain is so lost

I feel like I can be dumb as nails, I spent the last two weeks trying to mod a game but didn't realise my files were in the wrong spot lol

For this instance it more how do I make sense of all this information....if anyone an artist here I'd love some useful warm ups to help practice backgrounds for drawing comics without overloading myself....
