I think in the total collapse scenario, you must account for the possibility that you will have to move in order to survive. Some people seem to assume total collapse means the disappearance of government and public services, with an occasional mob here and there. There could be invading troops, and your neighborhood could be a battleground. Or there could be some sort of long-term natural disaster. You can't just stay and homestead like it was 19th century America on the frontier. Look at Syria -- how are you going to farm a patch of land and be "self-reliant" when ISIS might come and cut off your head?

You have to prepare for the possibility that you have move, possibly across borders. In that case,

-- Learn some foreign languages. If you can't communicate, you stand at a great disadvantage!

-- Travel and scout out potential countries to run to. Get to know their culture, law, and system. Make some friends there.

-- Keep your travel documents in shape.

-- However, be ready to sneak into another country without the proper documents or visas if that's the only path of survival. I'm not sure how to get expertise in human smuggling.

-- Money. Be ready for the collapse of your country's currency system. Don't count on the banking system to come through. You may not be able to access your millions in the numbered Swiss banking account if you are forced to Ogalaland.

What else?
