Anthem is a short story which condemns groupism and glorifies individualism. The story is prophetic, it tells what kind of backward and unhappy place this world would become if everybody stopped living for self and started living for others. So the message is to stop thinking 'We' and start thinking 'I'. I agree that 'I' is the key to happy and fulfilling life. Every individual is responsible for his happiness. Only if an individual is happy would he make the people around him happy.
