The irony here is that being selfish is actually what we all still are. Every decision we ever make is a selfish one. Every choice we make is because we think that is what will ultimately give us the most pleasure. Who we marry is the person we think is the best for me. What job we take is because that will be best for us in the long run. Every choice is a selfish choice. What we must learn is that greatest act of selfishness we can have is to be unselfish. To learn to give and be concerned with other people's pleasure is what ultimitely will give us the most pleasure. We see this so clearly in relationships; when we give we receive so much more. The challenge is learning to have a healthy balance between the realization that we are always concerned with what is best for us and the awareness that negating others is not to our benefit. When we focus on ourselves in a way that negates others that is what leads to the attitude of entitlement and narcisim. You are an intruder in my world. However when we realize that being concerned with others needs and pleasures is what gives me the most pleasure then we can learn to give in a healthy balanced way. Just like one should not take care of them self to the exclusion of others it is just as bad to give to others at the cost of our own self needs. We should look at the world as if it is our own. It is our own to get the most pleasure from. And the greatest pleasure we can get is by being selfish in the right way.
