learned about it fortuitously, organically, and synchronistically. and willingly.
at this point, from my point of view, saying you could never get into magick is like someone saying she could never get into blood circulation.
Blood circulation is just a part of being alive. Everyone’s already doing it; already circulating blood. Now, the decision to study it or not is another matter. And I agree with you. If the subject doesn’t interest you, toss it.
Then again I feel that way about most subjects.
The one subject that I think all human beings need to spend time on is Ethics. We’re just too fundamentally dangerous to not study ethics. (I’d also personally prefer if the doctors would continue to work on their craft. I’d be loathe to part with the engineers. And chefs.)

Magick and mysticism? Yes, for me they’re pretty crucial. But does everyone need to pursue them? hmm… nah, not in detail anyway.
But if you’ve ever felt awe, at anything, then you’ve dipped your toe in the pool. And awe is one of the essential vitamins for the human spirit, so magick definitely has its place. (people who go without awe for too long get sick. those who overdose on it, also get sick.)
anyway, practical version:
meditated for a long time.
as a boy, read Jung and co.
eventually, it was the right time to engage mental/imaginal structures more actively.
heard someone mention an author. read his books. tried the processes. felt right.
and that’s the story of how I learned about it.
