I clicked through a few of these videos. He talks in generalities. I am guilty of this in my own podcast, mostly because I don’t want to push one paradigm over another. He does some pretty good overviews of general concepts, but also makes some flubs. His definition of a grimoire is NOT the standard definition. In the classic sense, a grimoire is a list of spirits and how to communicate with them. The Lesser Key of Solomon is the most referenced grimoire. A grimoire is not simply your magical journal.
That all being said, he seems like a decent guy, and he goes to Gen Con so he gets points for that.
If you want to watch a youtube show featuring the hardest working magician on the internet, check out @billybrujo. The man knows his shit.
Something I forgot to add. You will never understand magick by studying magick. You only understand by doing. I recommend you change your plans. Start small. Do a sigil. Learn a banishing ritual. Make an ancestor altar.
Magick works and you will improve your life by doing it.
