I'm not a superstitious person at all, and don't believe in any of those symbols of "bad luck" - or the "good luck" ones, either (rabbits foot, 4-leaf clover, etc.). As you said, when your number's up, it's up.

Having said that, however, I am also a firm believer in sending and receiving positive and/or negative energy which affects our lives and those around us. I believe that every single thing in this universe has it's own energy and soul ... and I definitely believe in Karma (she can be a real bitch sometimes!). LOL.
