Most people think they're smarter than most other people. But, mathematically, that's impossible. You might have some wisdom, some insight, but there are a LOT of people smarter than you, especially in regards to specific issues. This is why political discussions often don't go anywhere. We all think we're right and have nothing to learn. Therefore, our argument becomes, "Shut up! Don't you understand how smart I am? Listen to me!" The moral of this story is to actively search out people who are smarter than you (they exist, trust me, even if you have to find them in literary form) and start learning from them.
