Why are you good at one type of magic but not another?
Some people are good at love spells but suck at money spells. Others are good at hexes but can't get career spells to work. Some people are great with divination and yet, can't get any spells to work.
I was always told it was because the caster has some deep seated belief that they are not worthy of XYZ, and casting for it won't dislodged it, you have to fix yourself first. What a long time to wait.
But I was also told that, if you just resonate at the correct frequency XYZ can't help but come.
And I was told about that it's days of the week, planetary alignment, time, etc. will make it come.
Or, if your into John Dee, magical thinking alone will ultimately make it come. Or if your into manifesting, magical thinking alone will make it come.
The most useful I ever found was to just forget the casting after it's done. Be unconcerned and it will come. Always work for me.
So that's it, why do things come for one but not for another? Why are we good at certain types of magic but not others? Why do you think this is? Not what answer someone presented you, what answer did you find?
