People care about others. They want to be liked by others, even loved by them.
When we are separated from others we experience loneliness, one of life’s most unpleasant emotions.
We develop and maintain our relationships with others through the fundamental motivation of other-concern
Other-concern refers to behaviors we engage in that directly help others, including moral behaviors, altruism, and cooperation.
We feel good about ourselves when we engage in other-concern, often even better than we do after doing things that benefit ourselves.
