When I was younger I was one of those people who was like, I want world peace blah blah blah. Now at my current age I see that world peace is a relatively stupid thing. See if the world was at peace, yeah everyone would be safe, but it also means there are basically no emotions. For the world to be at peace people can't be sad or anything like that. Imagine that, you just don't have emotions, fun no longer exists, it's not as happy and joyous as you thought, right. If the world was at peace think about how many people would lose their jobs, wait, who would need jobs if the world was at peace. Creativity would cease to exist for everyone is equal. For the world to be at peace there cannot be difference of opinions. If the world was at peace just think of all the things you would lose, is that really worth the few things you would gain?
