How do you make the world a better place? By being a better person. Just one can make all the difference.
It is easy to allow your reach to exceed your grasp. No one can reasonably expect the impossible. But people become quite nervous when you point out what is well within their capabilities.
Being good is not easy. The envious will desire to take what you have. Others will hate you for making them look as bad as they are.
Why would anyone want that? It easy not to care: you just do nothing. There is a perception of safety in apathy.
But what does it bring? They get as good as they give, leading empty lives filled with deep depression. There is no escaping the nothingness within.
Sometimes it hurts to care, but it also helps. There is a reason our eyes look out and not in. If we close them, our world becomes a dark place indeed.
