good question. given the corruption we are surrounded by, and the volatility evidenced by history, it can easily become a concern to start doomsday prepping. Lord knows there is always a conspiracy site yelling the economy will crash next week and the only solution is gold and water filters. i have a little insight here based on my mistakes (gen x oldfag here)
people went prepper crazy for Y2K and nothing happened. people went nuts over 2012 mayan calender. most uneventful day ever. really in my lifetime there have only been a few notable events. 9/11 (really the only effect here was paranoia and the loss of personal rights, the 84 recession and 2008 housing bubble bursting (lots of money lost, but still a controlled contraction to consolidate power, not a collapse) Far Leftism/sjw/jewish cultural decay (which has created cancel culture) and the immigration crisis (not accelerated to a level that is disastrous for our future.
i thought collapse was coming. i bought the water filter and survival seed bank. never actually needed them, or the other prepper gear i bought.
what you need to do is be a "common sense" prepper. prepare for car breakdowns, look into the history of weather issues/natural disasters in your region, save and stock up like you might be unemployed for a few months, imagine what you would do in an extended power outage, or if the supply trucks stopped coming to walmart.
best advice i would have given myself: HEALTH IS KING. become the most annoying intolerant person on earth when it comes to what you will and will not put in your body. do full body weight lifting routines, hiking, sprints, MMA (need striking and jiu jitsu) take shooting courses. carry concealed. the most likely self defense scenario is and will be someone trying to fight you in a store, parking lot, or road rage situation. practice situational awareness, know how to get away from someone, or brutally dominate if you have to.
dont trust the stock market (even though i dont believe it will ever collapse. it will be maintained so the feds can keep control.) they want you in debt, poor, sick, weak, confused, alone, divided. they fear a strong educated and militarized group of people who understand how evil they are.
i dont regret stopping the pursuit of college degrees after my first one. i dont regret the self education i did through books and online (truth is not taught in school or on TV for a reason) i dont regret the "common sense" prepping i did as it did help me weather a few hurricanes and later snow storms. i had the $100 cash for a tow instead of some ripoff like AAA. i had a larder of food, and the basic products i use to endure 2 months of unemployment. i feel much safer now that carry concealed.
the key here is to prepare for practical scenarios like i listed earlier. the future will be browner, poorer, legally more hostile to whites (corporate policy will also be) infrastructure will become undependable, cities uninhabitable. once again HEALTH and resiliency matter most. Local human networks because the government will not help you, but a church, gun club, bowling league etc will. these are people you can call for help.
we are already in nascent anarcho-tyranny. this means selective enforcement of laws like we saw in Charlottesville, big tech censorship, twitter lynch mobs etc. it will be worse when all of these brown people become cops, judges, mayors, CEO's etc. i am in the process of switching banks because of how "woke" mine just became, and all the call center people, including the manager, are brown people who i know are fucking with me, and i dont trust them.
vote with your feet and move to a better place, but dont expect it to stay white and conservative. those areas are targeted too.
be able to go mobile if you can. if there is a disaster the best bet is always to be away from it.
