I'd say I'm a little like a Utilitarianist that follows psychological egoism, if that really even makes sense.

Utilitarian - One ought to create the great good for the greatest amount of people, or decrease the greatest amount of suffering.

Psychological Egoism - People do what they think is in their best interest.

Although those are very contradicting in defiinition, it is the best medium ground I can really think of. Of course, I try to follow those definitions, but with a certain amount of restriction. Like the Great John Nash said in a Beautiful Mind, you shouldn't do what is in the best interest of yourself, but rather do what is best for you and for the group, which would kind of encompass the previously two mentioned definitions.

I'd like to pursue my true self interest, but with trying to keep others in mind through the process. Get it?
