I'm not usually the guy who believes in aliens, UFOs or superstitions.
Something I'm going to try to really instill in my own family is a lot of tradition. And, I used to have a lot of superstitions, and then I realized that it was kind of hogwash. Once I let go of them, I relaxed a lot.
We are often told by our friends and family members to not go to a particular place owing to some unkown energies that might have existed there, making us form superstitions in our mind.
Basically I say a few prayers before a game and let that direct me, not superstitions.
Superstitions and belief in magic are perennial in just the same way as religion, and something near to being universal among mankind; and why this is so may be interesting, but in most cases the beliefs themselves are devoid of interesting content, at least to me.
I actually rid myself of superstitions, but I do a quick 20-minute meditation before games.
I am saying that while popular culture usually portrays practitioners of magic as separate from ordinary people, often biologically different, many people have habits or customs or superstitions that show magic was once a whole lot more democratic.
