It sounds like you've already realized you're drinking from a fire hose. There is no possible way to consume all information. It is being generated far faster than you could even hope to consume in many lifetimes.

Since you can't be informed about everything all the time pick a topic or two that you are deeply interested in learning more about (or keeping up to date). Then enjoy the fact that you can tune out the fear stations (CNN, Fox News, etc.) and concentrate on your specialty. Because most other people won't know nearly as much as you about your selected topics you may be perceived as far more informed than others.

I get a weekly business magazine and used to be vigilant about reading every article every week. Now I just skim the headlines and dig into something if it's interesting. I'll even throw out a previous week's magazine if a new one arrives. Anything important enough from the old issue will be in the new one.

The other advice that I can give is to pick the most important item/article and put 100% of your energy to accomplishing your goal by a specific deadline. Then move onto the next goal. My brain is much happier processing in serial instead of parallel.
