Do things you read or hear scare you about the future? Or do you take note and go on with life?
I've discovered that some of the preppers' videos I watch are scaring others in the household. Those videos don't scare me at all. Instead of fear, I feel better informed and more prepared. And I get valuable ideas.
I don't think there's any reason to be scared if there's something you can do about a situation.
There may be a reason to be scared if there's nothing you can do about it, but fear is still probably pointless. If a planet-killer asteroid is heading toward us, fear seems like an understandable reaction, even if it's not productive since there's nothing you can do about it.
But nothing I've heard from any preppers is reason to be scared. They are reasons to prepare.
I'm not scared of Mad Max world-- I don't want it, but I'm not scared. I don't want my daughter to feel hunger when there's nothing I can do about it. That's why I prep. She might be more concerned about a world without "social" media, but that seems like a beneficial development to me. We'd push through that "crisis".
For most of the situations preppers discuss, I feel I could navigate my way through them. Maybe that's false confidence. I've made it through a lot of things that could have killed me. Looking back they don't seem nearly as difficult as they did at the time, and most of them taught me things to avoid.
I don't think there's anything to be scared of-- no, not even authoritarianism. Just keep learning and be open to better ideas. And try to help calm down anyone around you who is afraid of the future. Panicky people around you isn't going to be helpful.
