If you pass the time at work daydreaming about how you’d rebuild and create community after a civilization collapse, take a little time every once in a while to build up the skills and experience to do that
Learn how to fight or shoot a gun. Read about herbal and DIY medicine, and start growing some of those plants yourself. Get into graffiti, shoplifting, dumpster diving, or sabotaging security cameras so you can build up experience with getting things done in secret and getting away with them. Learn how to lockpick, repair holes in clothing, grow food, start and utilize a fire, build and fix things, etc. Get a couple friends together and start a little mutual aid distro, and let it grow organically over time. Get into ham or CB radio or long-range wifi meshnets. Get to know your local activist scene. Get to know your neighbors and your coworkers, and talk to them about the things that bother or worry you and how you could start fixing them together
Maybe that collapse comes and you’re a little bit more prepared to build a better world. Or maybe it doesn’t, and you can get started making yourself and your community a little better and more independent anyway. Either way, taking a couple hours every week to build some skills and get some stuff done can make you feel so much less helpless
