Selfishness...!!!

What do you think about selfishness ? Till few weeks back, my thought would have been always thinking about oneself and all the actions based on thinking about self. But now i've got a more deeper thought or rather insight into selfishness. I got to know this from a friend of mine. And this is how it goes, Thinking about one's own self and actions based upon that, is not selfishness but it is expecting others to act according to one's own thought and thinking. Basically expecting others to live a life based on one's own expectation..!! This is what selfishness is.... Let's try not to be Selfish..!!
