The less I read the news and the more I read books, the happy and more informed I've felt. Neil Postman's book Amusing Ourselves to Death talks about "news without context," how the Queen of England having a cold does not in any way impact my life and there is nothing I can do about it.
In a way the news lately seems more exciting and terrible, and I definitely don't make light of it, but ultimately I can't really do anything directly to affect it other than voting and donating to causes I believe in. And so I try to do that and feel that that is enough. Humans are not capable of handling a world's worth of information.
Nassim Taleb argues in the book Fooled by Randomness that day to day, the behavior of things like the news and stock market prices are almost completely random. Only when you look at it from a monthly or yearly view do you actually see signal in the noise.
