Dude comes on as all "I need to learn this stuff for my and everyone's own good..."
Then is like "Oh I also curse people if I don't like 'em."
I find magick more successful if I do so for my own success and Protection. This has the effect of balancing things enough where if someone had it out for me, they would end up in some accident or something.
Not that I'd wish anything directly upon them, but having all your wheels balanced and putting forth your will in terms of protection and life success, $hit like that happens man.
I would suggest a heavy dose of something natural and psychedelic, to dissolve you in the cosmos as a drop a mongst many many other drops, and see that whatever you perceive is you, and wishing something upon anything is wishing it upon yourself.
Magical self protection if performed almost daily is all you really need after that. Though it is kind of funny to hear that someone had it out for you, after you felt sorry for them because they got into a car accident or something.
Instant Karma's gonna get you
