That’s sort of only answerable by your own experiences and there are plenty of people here who would say hey that’s what magick is for, to make change.
When you look through @Verdo’s repository of fantastical success stories,
you can be left with little doubt that some of those results would be near impossible by normal means.
If it is true that we are all stuck within our own destiny then that makes doing magick the equivalent to playing hopscotch in our spare time. What is personally verifiable is when you do a ritual on yourself for an intended change, such as to make yourself feel better emotionally or to open yourself up to something.
If you try that and you see an improvement then you can say that you took charge and made that happen and you might notice some things that usually get in the way suddenly wasn’t as much of an issue this time around and you might find things flow in a much better way.
