Being nice does not come out of goodness or high morals. It comes out of a fear of displeasing others and receiving their disapproval. …It’s making sure others like you and don’t have any negative feelings. No upset, confusion, boredom, irritation, sadness, hurt, anger, or fear. No discomfort whatsoever. Just happy, positive, approving thoughts and feelings. At its core, being nice is about being liked by others by making everything smooth. No waves, no friction. It’s based on this (woefully inaccurate) theory: If I please others, give them everything they want, keep a low profile, and don’t ruffle feathers or create any discomfort, then others will like me, love me, and shower me with approval and anything else I want. …The opposite of nice is being real. It’s being direct, honest, and truthful. It’s saying what you really think, expressing how you really feel, and sharing what’s true for you in that moment. This authenticity allows others to see and know the real you, which allows you to really feel love and connection.
