I agree. Maybe a few people are born to change the world, but most of us can’t bear the weight of the world on our shoulders. But we can change OUR world. The things we do, the way we act and interact with others, the things we say. The world will turn with or without us. Focus on being a good person. Do good things. Let your actions speak for you. Ranting rarely works.
In this world of information (often negative) overload, it is necessary to take breaks from it. I personally don’t watch the news. If anything important happens you will hear about it. There is no escaping it. But a daily dose of the worst of mankind is just depressing.
