In my opinion, to be a good person, one must do good deeds on a regular basis. I take care of my family's needs on a regular basis, but I don't consider it a good deed. I think a good deed can occur when someone goes out of their way to perform something without expecting anything in return.
I don't really think of myself as anything at all. Definitions do not apply. I don't restrict myself to only being one thing. A house that is empty has no selfishness, resentment, or any other form of greed. I am simply what I am, and that defies all explanations.
