However, I don't believe that the world will necessarily be worse in 100 years (though, if the apocalypse comes... hardeeharhar). I don't always think that I will lead the world to a better place, but I believe I have the power to. Saying there's no hope in the world means that you believe there's no hope for yourself... which I can definitely relate to, but don't agree with in a hardcore sense.
The future belongs to us, but not everyone agrees on what a good future is. What defines a "better" future? At this point, I'm not sure what would make a better future... but there are some things that would help for sure.
Peace would always be good, yeah, and maybe we have the power to do that. Maybe being a little bit nicer to people, connecting a little more, making that little bit of effort. A friend once mentioned to me that a smile can change the world... maybe smiling more would help us out. Maybe smiling more would give us a little more hope.
Or maybe less judgement? Less hate might give us some more hope. Respecting people could give not only the judged people, but I think the judging people as well, a little more hope.
I'd definitely like some more world awareness - Invisible Children is helping with that, at least for one aspect (great organization, BTW... if you can, donate! They're wonderful. Check 'em out). But poverty, hunger, and so many other illnesses affect people around the globe. In a better world, we'd need to fix that, and I think most people would agree.
I don't quite know what other things I'd do to make the world better. I do believe we can have a better world in 100 years, I'm just not certain we're all quite sure how.
