good circuitry design videos (repost since i used the wrong thread)

Jul 21, 2019
i posted in the wrong thread, but basically I never understood anything about circuitry design but I've always wanted to. After watched the Electronics 101 videos and understanding the concepts (and I can understand some basic schematics (and have even made them in KiCad)), I still struggle to converting a simple schematic to a PCB and making a circuit. I've tried to follow a video or two from YouTube showing off KiCad but I never understood it much - how all the layers work (soldermask, etc), how vias and holes work, where ground is, etc. Do you guys have any good videos on PCB design?
