#4. Rewards can break personal relationships.

Usually, people compete for tempting rewards, which causes envy and conflict. Such competition will surely do damage to relationships among people.

For example, a teacher might say, “if we keep behaving, we can have an ice cream party after school today.” Hearing this news, every student becomes super joyful and actively performs their schoolwork. But when school is over, the teacher says: “Class, because Maria did not behave well, I am sorry to announce that the ice cream part is canceled!” At this point, every child would be disappointed and even angry. They will vent their anger on Maria.
