Doesn't it all seem a little too arrogant? You? Change the world? By telling others to change themselves? It's not just naive but completely egoistic and ignorant. Above all, like I mentioned earlier, arrogant.
The world will not change for you. The world does not function on prayer. The world does not care.
It starts to get really annoying when you hear pleas to give a damn every morning - especially when you've been taught that pretty much no one's even going to look at you, let alone care.
