Do you have any little superstition sort of things you do?
Like, I prefer if the speed on the treadmill is an even number, so I'd rather be at 4.0 or 3.8 and not 3.9.
And I still, when I'm talking about certain things, knock on wood to like, un-jinx myself. Even if there's no actual wood around. Knock, knock, knock. (And if I think about it, I probably follow it up with a triple knock on my head too because I first learned it as "Knock on wood, hairy wood's best." Which I'm now realizing might look odd to people...)
