First: Don't keep much money in the bank. There is no decent interest to be earned anymore so why leave your money in the bank for the bank to use? Pay off your bills! Pay off credit card debt! Pay extra on your house to reduce interest owed and bring payoff down. Use money for improvements. Insulation for example.
Second: You need a van or a used UHAUL truck or something you can haul stuff with and sleep in if it ever becomes necessary. There is a lot to be said for used school buses.
Third: Keep your mouth shut! Don't go on sites and talk on forums about all your preparations. Trust no one! Never show off! Never brag!
Fourth: Buy tools and equipment and learn how to use them. Can you weld? Everyone should be able to weld. Girls too! (actually women are excellent welders).
Fifth: Forget that "buy American" motto. You are trying to survive. Buy tools from Harbor Freight. They are guaranteed and just as good as name brand tools. I used Pittsburgh plumbing tools for years and never had a problem. I have several power tools in my shop from Central Machinery (both Harbor Freight brands). For home repairs they will work fine.
Six: Only buy land if you are going to live on it. You might show up someday and find someone else on your land and they don't want to leave. Unnecessary legal hassle or gun fight! Buy it and move on to it even if all you got is a storage shed. Put up no trespassing signs and get a big dog! If you live in a state that allows open carry, strap on your pistol and wear it. If you buy land, grow a garden. Small at first until you get the soil improved and have adequate fencing. Grow tomatoes and peppers in big pots if necessary. But grow something!
Seven: Become a world class scrounge. Look in dumpsters, cruise neighborhoods the day before the trash truck and look for curb finds. Shop second hand stores, garage sales, yard sales, the clearance aisles. Never buy anything new you can get for a good price used. Look at building sites for scrap lumber. Ask if you can have it !
Eight: Forget about money markets and certificates of deposit. Spend your federal reserve notes on things of value. Tools, Guns, ammo, silver, gold. Replace the engine and tranny and rear end in your vehicle and drive it another 250,000 miles.
Nine: Give up all that nonsense about sending all the children to college. They can't get jobs with a liberal arts degree. Send them to trade schools if you can find one. Learn electrical and plumbing and carpentry and welding and diesel mechanics and small engine repair. Something they can EARN with. Only future doctors, lawyers, engineers, nurses and teachers and scientists need lots of college. If your son or daughter wants to waste 4 years on art appreciation and you are willing to pay for it, fine. They can redecorate your house when you are dead because they will still be living at home.
Ten: You cannot afford foolish pride. Pride is what made men jump out windows during the depression. Do what you got to do to survive and take care of your family.
Got any ideas I didn't think of? I look forward to your input.
