Marshall Rosenberg, psychologist and founder of the Non Violent Communication, a method to help people learn to communicate in a peaceful and conflict-solving way:

Instead of playing the game Making Life Wonderful and enjoying the quality of natural giving, everywhere and with everyone, we play the game of Who is Right.

The game of Who is Right is a game in which everybody loses. It involves two of the most devious things human beings have ever come upon: Reward and Punishment.

Anything we do out of fear of punishment if we don’t do it – everybody pays for.
Everything we do for a reward – everybody pays for.
Everything we do to make people like us – everybody pays for.
Everything we do out of guilt, shame, duty, obligation – everybody pays for.
