Can't help but be reminded of a novel I read in university - Faith of the Fallen (Sword of Truth series). It wrote of similar theme (with a more focus on faith/religion), of how one must serve the greater good, humanity and the whim of his fellow men. Going down further, you go into the philosophical territory of individualism vs collectivism, how do you decide and balance your own moral ground, your 'selfish' needs and the needs of your neighbours.
That is one of my favorite books of all time. You're right ... it centers on exactly what this article covers. The people in the book were members of a culture that taught that it was selfish to spend time and energy on your own needs. Your duty was to sacrifice your needs and your life for the "greater good". The "moral" was that there is nobility in taking charge of your own life and making what you want of it, and that, in fact, it is from doing so that the greater good benefits too. The slogan that captures it all: "Your life is yours and yours alone. Rise up and live it."
Not selfish: the main character in the book would give up everything for the woman he loved. I have no idea how much it overlaps with Ayn Rand. But taken as its own individual work, I consider it one of the most profound things I've ever read.
He was very much inspired by Ayn Rand for that book; I can't find the article that quotes him on it, but the wikipedia article at least mentions the connection. Similar to Ayn Rand, I thought he was a bit over the top and heavy handed with his philosophy, but obviously that's just a subjective takeaway.
