Being Selfish is Hard Work

This is the real revolution in Ayn Rand's ethics. Ayn Rand's ethics is not about doing what you feel like doing... It's figuring out. This is why being selfish is hard work. It's figuring out what is really in my long-term, rational, self-interest...

Self-interest is not doing whatever whim comes. It is thinking about what is truly, rationally in your self-interest.
~ Yaron Brook, Stossel (episode 3)
