Compliments are a great way to show solidarity, cooperation, friendliness, and goodwill. When traits like individualism and hard work are culturally valued, being rewarded for your personal performance through the acknowledgment of others can be a very effective motivator. As it says on the World Compliment Day website: “If on March 1st every person pays at least three people in his/her environment or (social) network a genuine and sincere compliment we will definitely create the Most Positive Day in the World!”
