So, I think there's a lot we can do to make the world a better place! I really like Ghandi's whole "be the change you wish to see in the world" thing.
I believe very strongly in the ripple effect thing... If you smile at someone they'll probably smile at someone else and so on... And if you can brighten someone's day even for an instant... It can spread.
I think adults need to play more and worry less... children do this automatically, though we grownups often push our worries onto them. If we could get a giant game of tag going on our way to and from work...I don't know, I think it could work wonders.
What if we waved at people as we sat on the bus on our way to work, or in our cars on the way to the grocery store?
What if we looked people in the eyes?
What if we saw the humanity in everyone we meet? What if we came to the understanding that we're all doing the best we can with what we have?
...you may say I'm a dreamer...
Heh heh, I bet someone is regretting giving me the forum to broadcast my ramblings! :-)
