Watch any feel-good movie, and that nice main character is going to get dumped on at some stage in the movie. Their boss might be straight out of The Devil wears Prada, or their brother is the equivalent of Scar trying to take down the king of the jungle, but the point is that being nice gets you in trouble.
Being nice is something we’re taught from birth. When you’re three, you’ve not grasped that barging someone out of the way for the red trike is considered impolite so an adult says “play nice,” and we learn that it’s a good thing.
But fast forward 20 years and suddenly, being too nice can get you in trouble. It can even stop you from earning a good salary, finding true love, or inventing something you believe in.
