Worry makes us miserable and uncomfortable, but many worriers claim it keeps them prepared and safe from harm. And in a way, it does, but not in the way you’d think. Is it possible to stop worrying? What if worry is part of who you are?

You know you’re a worrier if you live by Mad Eye Moody’s exhortation for “constant vigilance!” Or if you identify with the heroes of Disney’s oddly recurring theme of anxious fish: Flounder from The Little Mermaid or Marlin from Finding Nemo. Or if you relate to Fear from Inside Out. But that one’s almost too easy.
