This isn't going to sound like a bad habit....but it is!
Washing my hands too much. I am obsessive about it. It seems I am forever washing them for one reason or another and it dries my skin out something horrible. I use a LOT of lotion because of that. I also keep baby wipes in my car for times when I just NEED to wash and can't.
Yeah, it's a bad habit. Okay! I'm obsessive!
