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.
I know it’s extreme but it’s the reality. For someone who is impacting by politics (say lost their jobs due to COVID), you can’t just stay on the sideline and ignore it.
You just have the great privilege of letting other people take care of that dirty work.
Is taking a news diet good? Absolutely. Lots of crap out there and a mental break is needed once in a while. But ignoring the suffering of people around you is just bad.
The question is really how to optimize awareness & participation with personal wellbeing. There's a big difference between getting psychologically clobbered by the outrage engines of social media or TV news, and being able to take in and understand current events in a way that encourages contemplation of how to best participate.
One way is to focus our attention and efforts on the things we can control as OP mentions. Another is to shift sources from fast/reactive news to more infrequent and considered sources. Another still is to participate locally and learn things firsthand.
If I were to go around, attaching my real name or face to my opinions as some form of "participation" in society, I would be quite fucked. I don't call that a privilege by any means.
One may also act on those views believing they are helping society, while consensus in society views those actions as detrimental. A recent example of this is the rioters and insurrectionists at the Capitol believed they were doing something to help society, whereas society judged their actions otherwise.
A possible solution to this conundrum is to focus one's participation on areas that are broadly agreed upon to be beneficial to society, so as to avoid accidentally becoming part of the problem, or simply minimize blowback from a disapproving environment.
This is a solution that is intentionally sidestepping any particular ethical framework, which may guide one's actions toward different tradeoffs.
Another thing worth considering is not all participation in society need be political at all, nor attached to your real name, nor known to your employer. Those are conditions you've attached to your response that were not part of mine.
