The inspiration is this simple quote: "The chief task in life is simply this: to identify and separate matters so that I can say clearly to myself which are externals not under my control, and which have to do with the choices I actually control." (Epictetus)
I held this resolution for about 5 months and it was profoundly glorious. It's not hard. Treat current events like Game of Thrones spoilers. Focus on what you have control over. Be frank with others that you are taking a break from the news cycle. If your results are anything like mine you will find yourself calmer and able to concentrate on what matters. Your mind wont wander to externalities you don't have control over.
At the end of it, you can go read Wikipedia for 30 minutes and be just as caught up as anyone else because you know the end result of the news cycle instead of suffering through it as it happened.
The goal of staying politically informed is not so that you will necessarily take direct action. It is so that you will be able to take direct action if it becomes necessary for you to do so.
As many others have pointed out in the thread, it is quite selfish for you to do what you did. Millions of folks do not have the food security, income security, or essential freedoms and rights which are secured to you. However, selfishness is not inherently bad. What is bad is the myopia and the willingness to be ignorant which comes with it.
At the end of "Game of Thrones", nothing of interest happened. We all just turned off the TV and went on with life. However, politics is not just on TV. Your username suggests that you live somewhere in California; I live in Portland. Not all of us have your luxury.
