You could learn something today or meet someone who educates you about an issue you thought you already knew well. These new facts could be uncomfortable for you at first because they don’t fit neatly into your world view. But it’s essential for you to accept what you learn and change your opinion if need be. You can’t carry on with your old beliefs once you have the new information. You’re too smart for that. Show people that you’re gracious enough to admit when you’re wrong.
