Do you have to get excited? Isn't it enough to do what you can, donate what you can, then get on with life?

Most people don't even do that much.

Psychology tells us that we can care, really care, about 50 people at the most. When the Internet and the media engulf us with the sufferings and wrongdoings of the 7 billion people on earth, we are overwhelmed.

And then there's the cold-blooded troublemaking - the alarmist stuff, the propaganda, the false accusations, the never-ending ethnic squabbles. That really wears us down.

To sum up, Rap. Never mind. You're doing okay.
