When someone says something that confuses you today, don't just reject their comments and walk away. The viewpoints that don't make sense to you are the ones you should try to listen to all the more: they are the ones that have the most to teach you. Start a conversation with someone you disagree with, and you'll find out what makes them tick. Your intellectual curiosity has been starving for input for a while now, and these kinds of conversations will satisfy it.
