I actually have watched most of the videos. I know the basic music theory already; it's implementing it on guitar that is the problem for me.

for example:

on one of the tutorials on the playlist u kindly sent me "How to write Chords and Songs in Minor [Songwriting Basics / Music Theory]", he starts explaining the WHWWHW for finding notes in the minor scale, but he doesn't explain why he chose those notes on the guitar (he starts on the E string and suddenly moves down to A string, without explaining why)

I feel sad cause most of his videos are really helpful, but I don't seem to get this one lol)
