I see you’re assuming quite a bit about your magic here. The idea of adept implies an end. This does not apply to magic in it’s practice. It may apply to courses, or even entire forms of expression, if you run yourself dry, but as a whole you will never become an adapt at a craft that cannot be mastered
TBH if you quit a course because a year is too long, when a year is really kinda nothing compared to how much time it takes to get even intermediate, you might be in the wrong business.
The question is whether this is the right material for you. I don’t see why you can’t continue this work in parallel with picking up a book and pathworking it. The two would probably play off each other.
I supposed depends on the course. Some courses are built to be a “Non ending” course. And I get that, characterizing levels of “adeptness” is next to impossible.
Not to say the people who make the course are informed on what makes something adept.
Honestly any course with an “end” is more of a lesson to me than a course. A course is set, and isn’t unset, if you want to keep moving there, so sorry if i use the literal term, but that’s the only way to do it.
A course is set, a lesson is learned. Learning doesn’t necessarily effect the direction, so that’s why it sound more like lessons to me
