"Have you ever noticed that practically everything you read justifies and reinforces your your own opinions and views on life? The same is true with our radio and television listening and viewing choices as well. In fact, on America's most popular radio talk show, callers often identify themselves as "ditto heads", meaning "I already agree with everything you say. Tell me more". Liberals, conservatives -- we're all the same. We form opinions and then spend our entire lifetimes validating what we believe to be true. This rigidity is sad, because there is so much we can learn from points of view that are different from our own. It's also sad because the stubbornness it takes to keep our heart and mind closed to everything other than our own point of view creates a great deal of inner stress. A closed mind is always fighting to keep everything else at arm's length".
