>>2043186Get yourself out of an urban or suburban environment as soon as possible, and buy a sustainable property with several acres, at least, for subsistence farming and being able to raise livestock for meat. Alternately, you could just go try to live in the wilderness, but that is harder to accomplish, and you may not be able to set up for yourself a permanent home without trouble from the state.
>>2043195I know you're French, and France has a very large reputation for it, but stop paying so much attention to fashions. Wear practical clothing that will last for a long time, and payoff when SHTF. You could even stock up on extras of those, if you want to, but people do not need very many clothes, generally. Make sure to plan your clothing around hard-work and wear-and-tear, so buy durable fabrics and materials.
