For an individual, one of the best virtues is the absolute egoism. And, mysteriously, this absolute egoism can come true through only the absolute altruism.The most precious thing to an individual is the self. This is because, if the self doesn’t exist, the world itself as well as all the creatures has no meaning. Therefore, it is essential and natural that we should have the mind, the absolute egoism, which values the self most. By the way, this egoism can only be realized by our behaviors which do other people good or make good results come into being inside them. Shortly, the best and unique way for the self is to help people change for the better.
