Rituals/Good Luck

I do not consider any of my daily acts to be ritualistic but I do have a few constant behaviors that I connect good luck with. One odd behavior that was introduced to me by a friend a few years ago is whenever I drive through a yellow light, I tap the ceiling. This action is supposed to prevent me from getting pulled over, getting in an accident and even bring me good luck. I continue this action because nothing bad has happened in the past after doing it. Another good luck behavior I have is when I find a penny heads up on the ground I always pick it up and put it in my shoe, this action is also supposed to bring good luck. I conciously know these actions do not truly help bring good luck but I execute them because I always have.
