Selfishness is not a pleasant thing to experience or be around. Selfish people think about what they want and need but do not think about others needs and wants. They usually lack friends because of that. The selfish person lies to get what they want. They will pretend to be your friend then guilt trip you into doing things for them.

It is been proving that the giving person has more joy than one who receives due to a chemical reaction in the brain.
