Bad Habits/Addiction?? 😩

Is there something you guys obsess over doing or are addicted to doing?? Here's mine ... it's random but something I have always done.
Since I was maybe 10, I've always had this obsession over cleaning my fingernails & making sure that they're all pretty much the same length. I'm constantly using one finger to clean under one nail, then the next and next until they all look clean and free of dirt. Then I'll do it again just to be certain. I'll allow them to grow somewhat long and then if one chips, I'll cut them all down and start again. It drives me insane when they're not the same length, or dirty underneath & I can't understand WHY! lol 😂 😩 
Don't judge me haha. Who else has a weird addiction/obsession???
