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 (promotions, sales, friendships, dates, sex, attention).
