When you learn about someone elses life and what they've been through it helps give you an understanding about yourself. Lets say you're talking to someone who's homeless; after hearing their story about how they became homeless (whether it be from bad decisions or just bad luck) you might feel a greater sense of appreciation for what you have. Hearing other peoples stories gives us a different aspect to our own life. You might come to realize that you're either a better off person than you thought or even worser off. Hearing other stories might also help you reflect on your own. That will help you become a better person.
