Following the news on a daily basis is similar to day trading in stocks. It causes you to react to short-term fluctuations in world events (usually the negative ones), instead of seeing the long-term trends (which are mostly positive).
Don’t get sucked into the drama of the news media. You’re not going to get the whole story anyway. And whatever interpretation you get, will likely be biased. You’ll get pissed off, or be saddened, over things that aren’t the way you think they are. Not to mentioned out of your control.
A life of fear and paranoia isn’t a life. You’ve got better things to do with your time. If you take care of the important things in your life, you’re probably already doing your part to make the world a better place.
