It is a battle every day to not live a selfish life. The way we think, act and carry ourselves it is easy to focus on ourselves only and not others.
Here is a perspective that takes the focus off self.
"This is the true joy in life: Being used for a purpose recognized by yourself as a mighty one, being a force of nature instead of a feverish, selfish little clod of ailments and grievances, complaining that the world will not devote itself to making you happy. I am of the opinion that my life belongs to the whole community and, as long as I live, it is my privilege to do for it what I can. It is a sort of splendid torch which I have got hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations."
George Bernard Shaw
