Meh, Ayn Rand is wrong, lots of people do things that they'd rather not be doing for the good of their family/friends/society. I'm not sure why so many people adhere to her antisocial musings. Sure some people only do things that only make them feel good. Altruism exists despite all the Randians attempts to morph it into something else so they can feel better about being greedy/self-centered/self-serving like them.
