Ask HN: Good resources for learning electronic curcuits and PCB design

I feel lost. I watched videos & read tutorials but it's all pretty advanced stuff and I really need some curcuit basics. They just assume I know WHY to put a resistor here and a capacitor there.

I know some symbol basics but how do I know where to put what and why?

Do you know some tutorials/courses?

My goal is to create my own PCBs for multiple pet projects and being able to repair old ones.
