What’s something you keep doing wrong on purpose?

I’ve been wondering: what small, persistent thing do you do that you know is technically wrong, but you keep doing it anyway? Like me— I always line up my eyeliner with my pinky finger pressed into my cheek, even though it warps the angle. It’s messy, but it feels right. Maybe it’s the only way the shape holds when I’m tired. Or maybe I just like the mess.
