Learn a culture, religion, lifestyle other than your own. Learn to smile and accept many faces. Learn not to fear what you don't understand. Learn to co-exist with people of different ideals. We, people, may grow up with different backgrounds, but we pretty much have the same goals: Become a better person and to help others. I strongly believe that people are generally good. Call me optimistic, that's fine. There will always be a few rotten apples, but don't let that give you a reason to go blind.
