Maybe being selfless is be selfish.

Human nature is to seek pleasure and avoid pain/discomfort. If Mother Theresa feels pain by watching others suffer while sitting on sidelines then she is Feeling Pain. If she jumps in and lends a helping hand then she feels Pleasure through helping. She is being selfish because she is satisfying her own desires to feel pleasure and avoid pain.

Mother Theresa is selfish…..

If this is true then everything we do is a selfish choice.
