I try to prioritise what is actually important to me and what is actually useful to me.
Trump tweeting something rude? Has little impact on my day to day. Other than something to laugh about with work people later it's not relevant to me personally.
A shooting in a different state?
Sad as f*ck, scary, but not something I really need to know about, It's also unavoidable.
If you have any interaction with people day to day, someone will talk about it.
Why don't I need to know?
Simple.
It's rare, super rare.
You can't avoid hearing about the bullets, the bullets themselves never went anywhere near you.
Mass shootings happen rapidly and without warning. If it's going to happen, it's going to happen, there's no way to avoid it, or prepare for it.
All you can do is be observant of your surroundings. If a shooting starts, everything you can do about it is going to be reactive, not proactive.
This makes what happened at every other shooting prior is pretty much useless to you at that moment. "Don't get hit by the bullets" is the key point of surviving being shot at. I don't know about you, but I don't need to be reminded how bad bullets are for my health. I don't need a lineup of corpses paraded in front of my morning coffee to wake me up in the morning.
A shooting in a different place, different gunman, different crowd, means different tactics to survive.
I don't need to torture myself with other people's suffering.
I need to hear the shots that are going off near me. All the ones fired hundreds or thousands of miles away, don't matter to my immediate survival. The ones that are snapping over my head do matter, those are the ones I need to pay attention to.
I don't need a news anchor to tell me when I'm being shot at.
Natural disasters are another thing that's not helpful to be afraid of. A volcano erupting in the south Pacific, doesn't mean I have to worry about volcanoes. Where I live, if a volcano actually becomes a danger to me, the whole earth is f*cked. So why obsess over it?
Flooding? I can't swim.
Wildfires?
Someone will bang on my door to forcibly evacuate me, if I somehow fail to notice the smoke, glowing horizon, precooked animals and people all running the opposite direction with as many of their belongings as they can carry.
Full scale thermonuclear war?
Who cares? We're all f*cked if that happens.
I remember how to do "Duck and Cover". It's useless but hey, it's something to do while I wait for the last light show on earth.
As for people talking about me behind my back? Pffft... People do that no matter what. If they wanted to get the actual facts, they could just walk over and say hello.
My being aware of it doesn't do anything but make me self conscious, which is not helpful in any situation, so I can't be arsed to care about vacuous people.
How we react to a dangerous situation is of course unique to each person, but there's a few things that universally don't help.
Being burnt out from lack of sleep due to worrying about possibly being shot at, makes you slow to react, quick to panic and more likely to die.
How is that helpful?
The really bad news, you'll hear about it.
The good news is however something I like reading.
My preferred source for filtering out the bad news is a the subreddit "uplifting news". Lots of good stuff in there.
