  1. In reality, brains go overboard with this sort of fear validation. They love any chance to prove a fear is valid while ignoring all the reasons it's not.
  2. Praise is a judgment. It says, “I like the way you look or perform.” Validation demonstrates acceptance. It says, “I accept who you are, independent of how you look or perform.” When people claim that we shouldn’t rely on “external validation,” they are confusing validation with praise.
