This is a tough question. As a single person living alone I live a very selfish existence by default. I am able to do what I want, when I want and not have to consider anyone else when making these decisions. When I first started living this way it made me uncomfortable but now I have come to enjoy it. Does this make me selfish?
Hmm sorry, I didn't actually answer your question there. I guess I was trying to say that it's relative to your situation. A single person can afford to be much more selfish compared to someone in a relationship or someone with children.
You're welcome :)
You can't help others unless you take care of yourself first, meaning having basic needs met with a modest degree of comfort.

To stay barely alive.
At the very least you should be selfish enough to take care of yourself. Beyond that, I don't know if I could choose a definite limit.
To every extent. People seem to think that selfishness is bad, but it's the nature of every animal. Look out for number 1 above all else.
