Anyone have superstitions?

Just curious to know what superstitions some might have. When I say superstitions, I mean things or habits that you do regularly that you feel causes your day, or a particular event to go smoothly or just the way you want it. I.E. wearing the same pair of underwear to all of your softball games, and things like that.

I don't have many that I can think of off the top of my head, but I always put my left shoe on first. And when I played high school football, on every game day I ate two sausage biscuits and had a blue Powerade to drink for breakfast. We went 10-2, and the only times I didn't do that were the two losses, coincidence I hope.
