Changing yourself is inevitable. But what about changing the world?
Time for another quote. This one is attributed on the Internet to "Unknown Monk, circa 1300 AD" but that origin is highly unlikely considering the content. I don't care at all who said it, because it holds a lot of meaning for me.

World peace is a massive, lofty goal. To be honest, it seems unlikely in our current situation. But maybe the problem is that we've been thinking about it wrong.
