It is near impossible to effect the BIGGER world and what's going on it. However, you can effect your immediate world. A smile. A warm salutation. Or just maintaining as bright an outlook as you can to people around you can effect YOUR world and their world... even if it's just for that moment.
So don't stress trying to figure out the BIGGER WORLD, all that stuff OUT THERE. Look to and address YOUR WORLD, what is right around you, and make it the best you can because YOU CAN effect that.
Keep being amazing.
