What New Years superstition do you follow?

Four years ago someone told me to hold onto a dollar bill New Years Eve and not to spend it for the whole year. I did so and my husband and I got a new job. The following thing the same thing and nothing changed but my husbands job was closing up. So that year I decided maybe 100 dollars will do the trick and 2 months later he got a better job and 8 months later he got the job of his dreams. So for 2009 I held onto the first 100 and now a 2nd one hundred and my daughter got the job of her dreams, my son and husband both got job promotions as well. I don’t believe it really has to do with the money but I’m too worried to spend it. LOL Don’t want to risk a good thing. Do you have a superstition you can’t let go even though you may feel silly about it?
