Everyone misses out on something, so of course you are right. Whether it results from my "rigid" attitude and/or train of thought is debateable, but even that is a personal choice. One thing that studying and participating in "mystery tradition" groups (e.g. Qabalah) will teach you is that it is pointless to have regret for the past, because it cannot be changed. One should only live for their intention for their future, and make sure their intention is pure. "Magick" is nothing more than bringing significant personal focus to bear on your intention. And the "k" is specifically used to distinguish it from "magic" in that science is at the foundation of "magick".
It is highly effective, and as I have said many times before: There is no technology (and that is what magick is) that is evil. There is only evil intention in how and why you apply a technology. It is why I maintain that HDRKID's intention for spreading gloom and doom is evil. But the HDR itself is not. There...now we are back on topic!
