If you were given a chance to change the world what would it be and why?

Well, I think there is a lot of sadness and negativity in the world today, so I would probably change everyone's point of view to a much happier and positive one. Some people lead on a sad life, and it's hard to enjoy life while you're sad. It's so much fun being happy, and people deserve to live a life full of happiness while they have the chance.
