I believe in the power of positivity, because I see it in action all the time... I am positive and thus I attract positivity and see the positivity in the world. It's a personal thing, it makes my life better and hopefully it rubs off on some other people through me and makes their lives better, and hopefully it rubs off of THEM and makes some other peoples' lives better, and so on. I don't buy into the stuff that's being said here about some higher power organizing events though. We have responsibility for our own outcome, through our own means, attitudes and actions. This is just what I choose to do with my little part of it and it works for me. I choose not to watch the news because it depresses me, because indeed, a lot of terrible things are going on in the world. But a lot of good things are going on too and without the negativity filling my head it's not hard to see it. I also moved to a place where I feel a lot more positivity from the average person for the same reasons, because now I'm surrounded by like-minded people who don't inspire negative feelings in me.
There's not much I can do about conflicts around the world or social problems, all I can do is try to be a good influence on people (like my cousin who has turned into a raging homophobe/racist/hate-filled person, I do my best to influence him towards being more rational and loving, without preaching to him or otherwise turning him off to my input).
