The news. We need to be informed but sheesh. The network news focuses only on the tragedies. That is why I love to watch Science Channel, Nature, Discovery, etc. because they run programs on cutting edge developments. The positive stuff.
I am an optimist, Diana, but I don't know if even I can say "most" humans are wonderful, loving and giving. It safer to say that "some" are. The rest live life without a whole lot of awareness outside of hand-to-mouth survival.
