Do you ever, even lightheartedly, follow a superstition?

I know it is a mental thing for me, as in subconcious sugestion. As a child my mom would relate numerous superstitions to me from the "old country". One that I defied several times and sufferred negatively each time was the, "sing before breakfast you will cry before supper".

I used to knock on wood, but with it being used less and less in work place environments I stopped.

Oh and I don't watch the Gators play live on tv. I will listen in the other room and watch the replays. 

Yeah, the whole "Don't Jinx me and talk about too soon" . . . Occasionally "Knock on Wood", but mostly to illustrate how important something is to me.

I try to avoid cracks in the sidewalk.

When I was younger, yes---Step on a crack, break your mother's back; spill salt, throw it over your shoulder; etc.  And some from childhood as an adult when I was experiencing for the first time----sort of like "Oh, I know what to do immediately---and you do it without really thinking."

But I only do each once unless I'm passing on a tradition.

If I see a penny on the floor and it's heads up I pick it up because it always turns out I need that ONE penny (such as that one penny is the cent in a total of say 2.06 or 9.99 and I only have 3 pennies had I not picked up that heads up penny.) If the penny is tails up I leave it cuz if I pick it up I will be one penny short! Lol!

If I put an item of clothing on backward, I still get a twinge of " Oh no ! " It is a left over superstition from my childhood.

Break a mirror 7 years bad luck?
